This change does not + change the default behavior of the code. + + Changed the definition of local data minimum from the minimum pixel + in the centering box to the minimum median value for each row in the + centering box. This gives a value much closer to the background values + and protects against very low valued pixels in the centering box defining + the thresholding level. + + Davis, Sept 29, 1995 + +apphot/fitsky/apskybuf.x + Changed the misleading error return code from AP_SKY_OUTOFBOUNDS to + AP_NSKY_TOO_SMALL in the case when all the sky are out of the good + data range. + + Davis, June 22, 1995 + +apphot/daofind/apfind.x + Added a check to avoid a divide by zero error in the code which computes + the x and y positions of the detected objects. The divide by zero error + can occur when the datamin value is too high for the image and there + are not enough points to accurately compute the new x and y position. + + Davis, June 19, 1995 + +apphot/aplib/mkpkg +apphot/aplib/apwres1.x +apphot/aplib/apwres2.x +apphot/aplib/apwres3.x +apphot/aplib/apwres4.x +apphot/doc/phot.hlp +apphot/doc/polyphot.hlp +apphot/doc/qphot.hlp +apphot/doc/radprof.hlp +apphot/doc/wphot.hlp + Added a FLUX column to the output of the PHOT, POLYPHOT, QPHOT, RADPROF, + and WPHOT tasks and updated the appropriate help pages. + + Davis, Nov 14, 1994 + +apphot/daofind/apfdstars.x +apphot/daofind/apbfdfind.x + Added a missing check for an INDEF value of sigma that could cause + a floating point overflow in daofind when run from the APPHOT package + with the default parameters. + + Davis, Oct 20, 1994 + +apphot/aplib/apwres2.x + Added a check to make sure that the OTIME and IFILTER fields do not + overflow the 23 character space allotted for them in the output file. + + Davis, Oct 12, 1994 + +apphot/center/t_center.x +apphot/daofind/t_daofind.x +apphot/fitpsf/t_fitpsf.x +apphot/fitsky/t_fitsky.x +apphot/phot/t_phot.x +apphot/phot/t_qphot.x +apphot/polyphot/t_polymark.x +apphot/polyphot/t_polyphot.x +apphot/radprof/t_radprof.x +apphot/wphot/t_wphot.x + Fixed a bug in the default input and output file naming code which was + causing the directory specifications to be stripped from the names. + + Davis, Oct 4, 1994 + +apphot/phot/apphot.x +apphot/phot/apqphot.x +apphot/wphot/apwphot.x +apphot/polyphot/apyphot.x +apphot/radprof/apradprof.x +apphot/phot/phot.key +apphot/phot/qphot.key +apphot/wphot/wphot.key +apphot/polyphot/polyphot.key +apphot/radprof/radprof.key +apphot/doc/phot.hlp +apphot/doc/qphot.hlp +apphot/doc/wphot.hlp +apphot/doc/polyphot.hlp +apphot/doc/radprof.hlp + Added a new keystroke command 'a' to the phot, qphot, wphot, polyphot + and radprof commands. The a keystroke command compute a sky value + by averaging several sky values sampled in different regions of the + image. Basically it is a loop over the the t keystroke command. + The sky value in each region is computed using the current algorithm + and geometry and the individual sky, sky sigma and sky skew values + are averaged to produce a final sky, sigma and skew, whereas the + number of sky pixels and number of rejected sky pixels are summed. + The a keystroke command is intended for use with the p and o keystroke + commands to produce an offset sky measurement capability. + + Davis, Feb 10, 1994 + +apphot/fitpsf/apsffit.x +apphot/fitpsf/apsfrefit.x +apphot/aplib/apwres4.x + 1. Modified the fitpsf task fitting routines so that the parameter and + parameter error arrays are initialized to INDEF (instead of being left + with the values from the previous fit), in the case that the + fitting box is entirely off the image or that that there are too few + pixels in the fitting box to fit the model psf. + 2. Modified the output formatting routines to print the errors in + the fitted rsigma (function=radgauss), xsigma and ysigma (function= + elgauss), and rgyrat and ellip (function=moments) to three decimal + places instead of two. + + Davis, Jan 17, 1994 + +apphot/center/t_center.x +apphot/fitpsf/t_fitpsf.x +apphot/fitsky/t_fitsky.x +apphot/phot/t_phot.x +apphot/polyphot/t_polyphot.x +apphot/phot/t_qphot.x +apphot/phot/t_radprof.x +apphot/wphot/t_wphot.x + If the number of input images was greater than one, the number of output + files exactly equal to one, and the input coordinate file for the image + did not contain any decodable coordinates the coordinate file rather + than the empty output file is deleted. This was ocurring because the + output file was not being correctly stored each time through the image + loop and empty output files are deleted by the apphot tasks. + + Davis, Dec 31, 1993 + +apphot/fitsky/aprefitsky.x + The SCALE parameter in the call to ap_crossor was incorrectly + dereferenced as AP_SCALE(sky) instead of AP_SCALE(ap). + + Davis, Sep 13, 1993 + +apphot/aplib/apinpars2.x + The shiclip parameter, default = 0.0, was incorrectly being set to the + value of the sloclip parameter at startup time. + + Davis, Sep 9, 1993 + +apphot/center/aprefitcen.x + The CMAXITER parameter was incorrectly referenced in the call to + the ap_lgctr1d routine inside the routine aprefitcenter. + This centering routine is not often used, and the bug is trigggered + only if an object is recentered using different algorithm parameters + but the same image data, something only likely to occur in interactive + mode. + + Davis, Sep 6, 1993 + +apphot/center/apcencolon.x + The arugument cmdstr in the routine apcentercolon was declared as + "char cmdstr" instead of "char cmdstr[ARB]. This has not caused any + errors in the code but is poor style. + + Davis, Sep 6, 1993 + +apphot/phot/apgqppars.x +apphot/doc/qphot.hlp +apphot/fitskypars.par +apphot/doc/fitskypars.hlp + Changed the default sky fitting algorithm for the qphot and phot tasks from + "mode" to "centroid" with histogram smoothing, to minimize problems + with data taken at low light levels which have poorly sampled + histograms. + + Davis, Aug 14, 1993 + +apphot$ + The sky fitting routines were revised. Two new parameters, ploclip and + phiclip, which define the percentage of pixels to clip on the low + and high sides of the sky pixel distribution were added to fitskypars. The + fitskypars parameter skreject was split into two parameters + sloreject and shireject which define the low and high side rejection + parameters respectively. For the mean, median, and mode algorithms + the first rejection cut is now made below sky - min (smax - sky, sky - smin, + sloreject * skysigma) and above sky + min (smax - sky, sky - smin, + shireject * skysigma) where sky is the first estimate of the mean, median, + and median of the sky pixels respectively, instead of below and above the + skreject rejection limits alone. The median is computed using + the average of 5% of the pixels around the median instead of 10 pixels. + All the histogram dependent algorithms: histplot, centroid, gauss, + crosscor, ofilt now use the median of the sky pixels as the center + of the histogram, and define the extent of the + histogram in a manner similar to that used for the first cut in + the mean, median, and mode algorithms. The sigma parameter is + no longer used to define the extent and binsize of the sky histogram. + Instead the computed sky sigma is used. + + Added m and n keys to the apphot tasks. These keys operate in the same + way as the :m and :n keys which have no arguments. + + Added the o key to the apphot tasks. This behaves in the same way + as the p key but outputs the results to the output results file. + + Davis, Feb 24, 1993 + +apphot/aputil/apgflags.x + Removed this routine which was not being used and referenced gio.h from + the apphot library. + + Davis, Feb 11, 1993 + +apphot/daofind + + Added the findpars pset to the daofind task and removed the parameter + threshold from datapars to findpars. All the detection algorithm + parameters moved to findpars. + + Changed the name of the output convolved image to starmap. Added + an option to output the best fit sky image skymap. + + Davis, Sept 17, 1992 + +apphot$ + Modified all tasks (daofind, center, fitpsf, fitsky, phot, polymark, + polyphot, qphot, radprof, and wphot) that were designed to draw marks + on the image display to use the imd kernel. All graphics + drawing commands are done with portable gio calls. A temporary routine + which uses the imd interface to fetch the display device viewport and + window is called each time a new image is mapped. A warning message + is issued if the image is not loaded in the display and the default + full frame viewport is used. All display drawing is done to the + current frame, even if the current frame is not the frame containing + the image. The imd kernel does not support the gflush command so + a gframe command is used instead. This can create a messy metacode + file but is a reasonable approximation for interactive use. + + Davis, Sep 2, 1992 + +apphot$phot/apphotcolon.x +apphot$phot/apqcolon.x +apphot$radprof/aprpcolon.x +apphot$wphot/apwpcolon.x +apphot$wphot/aptmeasure.x +apphot$wphot/apgmeasure.x +apphot$aplib/apverify1.x +apphot$daofind/apfcolon.x +apphot$fitpsf/apppsf.x +apphot$fitpsf/apsfcolon.x +apphot$polyphot/apycolon.x + Added some missing sfree statements. + + Davis, Sep 2, 1992 + +apphot$fitsky/aplgsky,x + The test "if (ier != AP_OK)" was being made instead of the proper test + "if (iter < 0)".

The error output for rsigma in the fitpsf radial gaussian fitting + routine and for xsigma/ysigma in the elliptical gaussian fitting routines + in the old code was actually the error in rsigma ** 2 or xsigma ** 2 + and ysigma ** 2 respectively. These errors were too small. + + Davis, July 28, 1991 + +apphot$center/apfitcen.x +apphot$center/aprefitcen.x +apphot$center/apgctr1d.x +apphot$center/aplgctr1d.x +apphot$aputil/aptopt.x +apphot$aputil/apqzero.x + 1. Modified all the centering routines so that the fitted centers are + contrained to stay in the fitting box after each iteration. The gauss + algorithm in particular could runaway when fitting objects near the + edge of the frame or very weak objects. + + 2. Fixed a bug in the optimal filter algorithm wherein the + normalization procedure could fail if there wa no star in the + centering box. + + Davis, May 30, 1991 + +apphot$center/apcconfirm.x +apphot$fitsky/apsconfirm.x +apphot$phot/appconfirm.x +apphot$wphot/apwconfirm.x +apphot$polyphot/apyconfirm.x +apphot$radprof/aprconfirm.x +apphot$fitpsf/appsfconfirm.x + 1.

Modified the fitpsf task so the the radial gaussian and elliptical + gaussian fitting routines use the maximum (emission objects) or + minimum (absorption objects) pixel position as the first guess for + a good position instead of the center position. + + Davis, Nov 16/1990 + +apphot$daofind/apbfdfind.x +apphot$daofind/apconvolve.x +apphot$daofind/apfdstars.x + 1. Fixed a bug in the batch mode execution of DAOFIND wherein + DAOFIND quit with an "cannot write pixel file error" when run on + a previously existing convolved image. This bug was introduced by the + Mar 12 1990 bugfix. + + Davis, Nov 8, 1990 + +apphot$polyphot/t_polyphot.x +apphot$lib/polyphot.h + 1. Changed the default size of MAX_NVERTICES from 100 to 900 to satisfy + some surface photometry people. Removed a redundant MAX_NVERTICES + declaration in t_polyphot.x + + Davis, Aug 24, 1990 + +apphot$phot/apmagbuf.x + 1. Phot was refusing to fit stars whose apertures were < 1.0 pixels from + the edge of the image because the out-of-bounds criterion was too + conservative. I modified the code to remove this problem. + + Davis, Aug 6, 1990 + +apphot$daofind/apbfdfind.x +apphot$daofind/apfdstars.x +apphot$daofind/apfind.x + 1. Changed the daofind program to automatically include the relative + error in the detection threshold. + +Davis, July 17, 1990 + +apphot$fitsky/apskybuf.x + 1. In a few cases due to fractional pixel effects the skyfitting + routines were not preallocating sufficient space to hold the sky + pixels resulting in a memory corruption error. + + Davis, June 27, 1990 + +apphot$aplib/apfrprof.x,mkpkg + 1. Modified radprof so that it would integrate 2*PI*r*I instead of + just I itself. + + Davis, June 18, 1990 + +apphot$aplib/apfdres.x + 1. Renamed the round and sharp parameters to roundness and sharp to + remove and ambiguity in the naming convention. + + Davis, May 24, 1990 + +apphot$daofind/apconvolve.x + 1. Added an imflush after the last write in apconolve which cured + a "pixel file is truncated error". This error showed up when + daofind was run on an image that was 641 by 1025 but not on + one that was 640 by 1024. Apparently this problem has been there + all along but only occurs very rarely. + + Davis, Mar 29, 1980 + +apphot$aptest.cl +apphot$aptest.par + 1. Added the aptest task to the apphot package. + + Davis, Mar 19, 1990 + +apphot$aplib/ + 1. Fixed two bugs in the output formating code. Long file names could + overflow the fixed format space allotted and destroy the syntax of the + file making it impossible for apselect to decode it. Second the COORDS + parameter was mistakenly typed as integer instead of string. + Davis, Mar 14, 1990 + +apphot$daofind/ + 1. Fixed a bug which was causing daofind to fail to compute the convolved + image when the input and output images were in hhh format. The hhh format + was failing the test [if (IM_PIXFILE(im) == EOS)] as the pixel + file names are set at different places in the oif and stf kernel. + The test was dangerous and redundant, and has been removed. + + Davis, Mar 12, 1990 + +apphot$qphot/mkpkg + 1. Removed a duplicate entry for apqcolon.x from the mkpkg file. + + Davis, Feb 20, 1990 + +apphot$center/apcsnratio.x + 1. Recoded this routine slightly to avoid an optimizer bug in + the 386i version. + + Davis, Feb 13, 1990 + +apphot$center/apcinit.x +apphot$fitsky/apsinit.x,apsplot.x +apphot$phot/appplot.x + 1. The sky fitting algorithm string was not being correctly set if + salgorithm was "gauss" or "median" resulting in garbage in the output + file header. The correct algorithm was being used. + + 2. A floating point error would occur if salgorithm = "constant", + sigma = "INDEFR" and radial profile plotting was enabled. The problem + occurred because the plot was trying to draw the 3 * sigma of the + sky line by adding the sky value and the sky sigma which is INDEFR. + + 3. Disabled plotting the centering pixel buffer in the case where + "calgorithm" was none and the sky pixel buffer when salgorithm is + "none". + + Davis, Feb 7, 1990 + +apphot$fitpsf/apfitpsf.x +apphot$fitpsf/aprefitpsf.x + Fixed a bug in the weighting scheme for fitpsf in which the gain was + not scaling the image intensities correctly. I also added a check + for 0 valued weights. + + Davis, Jan29, 1990 + +apphot$ + Added a setup menu mode to all the apphot tasks. When the user types + i they enter the setup menu instead of a pre-defined set of commands. + The default setup is still available as the v key, but each parameter + can now be set individually as well. + + The documentation has been brought up-to-date. + + Davis, Jan 29, 1990 + +apphot$phot/t_phot.x + + Added calls to ap_airmass and ap_filter to the phot task as the filter + and airmass were not updating correctly. + + Davis, Jan 16, 1990 + +apphot$ + Four new parameters airmass, xairmass, filter, ifilter were added to + the datapars task to permit users to pick up the filter and airmass + quantities form the image headers for later transmission to calibration + programs. + + Davis, Nov 28, 1989 + +apphot$radprof.par + The default value of the verbose parameter in radprof was yes + instead of no as it should have been. + + Davis, Nov 28, 1989 + +apphot$ + Added a new algorithm "mean" to the sky fitting options. + + Davis, Nov 17, 1989 + +apphot$ + Added an update parameter to all the apphot tasks. If verify is yes + and the task is run in non-interactive mode update will update + the critical parameters into the psets. + + Davis, Nov 16, 1989 + +apphot$radprof/t_radprof.x + Removed a defunct define MAX_NAPERTS 15 statement from the + radprof task. It now uses the definition in phot.h like all + the other tasks. + + Davis, Nov 9, 1989 + +apphot$daofind/ + Changed daofind so that a new .coo file is output everytime daofind + is run in interactive mode. + + Davis, Oct 30, 1989 + +apphot$fitsky/apmode.x + Made some subtle mods to the mode fitting algorithm. In particular + only the first cut is made around the median the remainder are around + the mode. + + Davis, October 11, 1989 + +apphot$ + 1. apphot$center, fitsky, phot, wphot, polyphot, fitpsf and radprof tasks + Activated the datamin and datamax parameters. Pixels outside + this range are rejected from sky fitting algorithms and from the + non-linear least squares fits in fitpsf and radprof. If a bad pixel + is in the centering aperture or in a photometry aperture a magnitude + is still computed but a warning message is issued. + + The only task where these parameters are not currently implemented + is daofind, pending algorithm review. + + 2. apphot$polyphot/apyphot.x + Added a keystroke option to fit polygons that are not shifted to the + current cursor position. + + 3. apphot$fitsky/aprefitsky.x + Fixed an error in the stellar position reported on the plot in the + radplot option for sky fitting. The last cursor position was not + being reported. + + 4. apphot$fitsky/apmode.x + Changed the cut to one around the mode. Things look ok. + + Davis, October 10, 1989 + +apphot$apselect/apkeywords.x + 1. Fixed a bug in the apselect task. Apselect was not picking up changes + int the keywords (#K) values correctly. The pointer in the ky_addval + procedure was being incorrectly computed and the new value was being + put in the wrong place. + + Davis, Sept 15, 1989 + +apphot$ + 1. I removed the query for fwhmpsf from phot. + + 2. I fixed a serious problem in daofind when interactive = yes and + the task was rerun on the same convolved image but using a new + threshold. There was also a problem with the naming of the + temporary image. + + Davis, Aug 22, 1989 + +apphot$aplib/aprcursor.x +apphot$aplib/apradpsf.x + + 1. The prompt for the psf fitting box parameter box has been changed from + "centering radius" to "fitting box half width". + The prompt for the centering box parameter cbox has been changed from + "centering radius" to "centering box half width". + + 2. The code to quickly center the radial profile before fitting has + been added to the interactive setup routine. Somehow the fitpsf + task was overlooked when this update was made originally. + + Davis, Aug 1, 1989 + +apphot$aprcursor.x + The procedure ap_caper() inside apphot$aplib/aprcursor.x was define as + a type real procedure but called as a subroutine. I removed the type + real declaration. + + Davis, July 31, 1989 + +Version 2.8 export + +************************************************************************* + +apphot$ + 1. The inverse of the scale was being incorrectly printed out by + the :show command. + + 2. Fwhmpsf is in scale units not pixels as listed in datapars. + + 3. Exposure, ccdread and gain were not being updated correctly + in interactive mode. + + Davis, June 20, 1989 + +apphot$ + 1. A new parameter scale has been added to datapars and integrated into + the apphot tasks. All the radial profile plots will now display + units of scale and of pixels. The .hlp. .key and : commands + have all be changed appropritately. Testing is complete. + + 2. Some minor changes have been made to the quick look output formats. + + 3. A verbose and verify switch have been added to all the appropriate + tasks. + + 4. Daofind has been modifed so that the convolved image is automatically + up to date if any of the convolution kernel parameters have been + modified. + + Davis, May 27, 1989 + +apphot$ + 1. Add the verify switch to radprof and wphot. + + 2. Began separation of the scale and fwhmpsf parameter. + Scale was added to the apphot structure. + + Davis, May 17, 1989 + +apphot$ + 1. Fixed an error in the definition of the skyfile format in phot.hlp + and wphot.hlp. The are seven columns not five with the x and y position + in columns 1 and 2. + + 2. Added the verify switch to the center, fitsky, fitpsf and polyphot tasks. + + Davis, Mar 20, 1989 + +apphot$ + 1. Modified the prompts in datapars.par, centerpars.par, fitskypars.par + and photpars.par. + + 2. Added a confirm switch to the phot task. + + Davis, Mar 15, 1989 + +apphot$ + 1. Changed the interactive setup routine in daofind so that the radial + profile is centered before the interactive setup menu is entered. + + 2. A confirm switch has been added to the daofind task so that in batch + mode (the default) the user can check/confirm/modify the critical + task parameters. A similar 'v' for verify key has been added to + the list of interactive menu setup commands. + + Davis, Mar 14, 1989 + +apphot$ + 1. Edited the daofind parameter file to make the prompts more illuminating. + + 2. Changed all the daofind subdirectory procedure names beginning with + ap to ap_. This continues the apphot cleanup begun in January. + + 3. Fixed a bug in the interactive daofind code. If no convolution image + was opened daofind was trying to delete a nonexistent image at + task termination. + + Davis, Mar 13, 1989 + +apphot$apselect/ + I changed all the apselect subdirectory procedure names to begin with + ap_. This continues the cleanup begun in January. Moved the apkeysdef.h + file into the aplib subdirectory with all the other .h files. + + 1. Davis, Mar 3, 1989 + +apphot$ + I changed all the .keys and .skeys file extensions to .key extensions. + This removes a problem with installations which do a strip operation. + + Davis, Feb 3, 1989 + +apphot$apyfit.x + I fixed a potential problem in polyphot. If a user specified a concave + polygon and the image line intersected the polygon exactly on a vertex + polyphot might not be able to tell whether a line segment was inside + or outside the polygon, causing a error in the total flux computation. + The affected routine was ap_yclip in apyfit.x + + 1. Davis, Jan 30, 1989 + +apphot$ + All the tasks doing interactive setup using a radial profile now + center the profile before plotting. This facilitates marking the full + width half maximum of the psf on the plot. + + Davis, Jan 23, 1989 + +apphot + 1. Davis, Jan 21, 1989 + Began cleanup of file and procedure names. All file names now begin with + ap. All procedure names begin with ap. Eventually I will clean up + the ap to ap_ convention. The subdirectories polyphot and polymark + have been completely overhauled. Note caution about updates is in order. + +apphot + 1. Davis, Nov 11, 1988 + Removed a call to imparse in apimroot.x and a call to iki_parse in + apoutname.x. The calls were changed to imgimage. + +apphot + 1. Davis, Nov 3, 1988 + Daofind was outputing an incorrect magnitude estimate due to an indexing + problem. The correct stellar position was being output. + +apphot + 1. Davis, Oct 27, 1988 + The :aperts coomand in qphot.keys, phot.keys and wphot.keys was changed + to the correct :apertures command. The corresponding help pages were + also modified. + +apphot + 1. Davis, Oct 4, 1988 + The statement z = z + p[4] was out of order in the routine cdgauss1d + in cgauss1d.x. The evaluation of the derivative with respect to sigma + was in error. This bug would not be noticed in the apphot code as + sigma was being held constant whenever this routine was called. + +apphot + 1. Davis, Sept 12, 1988 + The APPHOT package was installed in the apphot subdirectory of the + digiphot package. + +apphot + 1. Davis, Aug 15, 1988 + If the i key (interactive setup option) was used after the first object + record was written to the database file then the changed parameters + were not being updated in the database file. The : commands were + being updated correctly. This problem has been fixed in all the + interactive tasks. + +apphot + 1. Davis, Aug 18, 1988 + Apselect will now accept a list of text files as input. + +apphot + 1. Davis, Aug 16, 1988 + The apphot tasks now save the apertures string as well as the list + of apertures. The phot, qphot and wphot phot tasks will noe accept + a ranges syntax of the form ap1:apn:apstep. This syntax can be + mixed with the former syntax. In addition it is know possible to read + the apertures from a text file. + +apphot + 1. Davis, Aug 11, 1988 + Fixed a bug in the angle computation for the elliptical Gaussian fitting + routine in fitpsf. Positive angles from 0 to 90 were correct, the + rest were being forced to be positive. + + 2. It is now possible to change the image, coordinate file and output + file name from apphot interactive mode. + +apphot + 1. Changed the maximum number of apertures from 15 to 100. + 2. Changed apwparam to allocate astring of SZ_LINE long. + + Davis, Aug 4, 1988 + +apphot + 1. Fixed a bug in polyget.x. The program was hanging in batch mode when + one tried to read a polygons file created by the imtool cursor readback + facility. I removed an incorrectly placed next statement. + + Davis, Jul 29, 1988 + +apphot + 1. Added id strings to all the parameter files which request + algorithm names etc. + + Davis, Jun 1, 1988 + +apphot + 1. I fixed a potentially serious problem in the way daofind handles + out of bounds regions. Daofind was accessing an out of bounds array + which accasionally would fail with divide by zeros NaNs etc. + The positions of stars near the edge of the image could be affected. + + Davis, Apr29, 1988 + +apphot$ + 1. Added a new parameter threshold and changed old parameter threshold + to cthreshold. + + 2. Daofind now reads the datapars file. It can now work on both emission + and absorption features. + + 3. Cleaned up the output and integrated with rest of apphot. + + Davis, Apr22, 1988 + +apphot$ + 1. Removed redundant MISC string definitions. + + 2. Added the DATAMIN and DATAMAX parameters required by daophot. This + required changes to the apphot structure, the get and put pars routines + and the set and stat calls. + + Davis, Apr12, 1988 + +apphot$ + 1. Added correct error code handling for the case where cbox <= 0.0 + or dannulus = 0.0. The correct action but incorrect error code was + being returned. + + 2. Fixed the same bug in the code for fitpsf. + + Davis, Apr4, 1988 + +apphot$ + 1. Fixed a bug in decoding the apertures string. If a nonsensical + apertures string was given then the apertures could be decoded into + some strange number. + + Davis, Apr4, 1988 + +apphot$apselect.x + 1. I fixed a bug in the apselect task which occurred when the user + requested all the output fields with the * command and the output + records contained array valued fields. The select buffer + was being allocated space equal to the number of unique keys, not + space for the total number of elements causing memory overflow + problems. + + Davis, Apr1, 1988 + +apphot$ + 1. Added a needed gdeactivate command to i setup key menus when they + terminate prematurely. Otherwise the terminal is left in graphics + mode. + + 2. A bug in the batch mode of running apphot tasks occurred if a single + output file was specified and there were no stars in the first file. + The header could be written several times and cause and error in apselect. + + Davis, Mar31, 1988 + +apphot$fitpsf/ + 1. I changed the initial guess for the sigma to be the fwhmpsf instead + of a small fraction of the fitting box as before. This affects both the + radial Gaussian and the elliptical Gaussian. + + Davis, Mar15,1988 + +apphot$ + 1. Floating divide by 0 errors were occurring in daofind when the threshold + was set to zero. These were arising in two different places. The + magnitude estimate is based on a ratio with respect to threshold + and the sharpness computation can blow up when the peak pixel is zero. + + 2. I have added a warning message to aptime.x, appadu.x and aprdnoise.x + so that they will print an error message if the header parameter + keyword cannot be found in the image header. + + Davis, Mar8,1988 + +apphot$ + The graphics and image device opens have been moved outside of the + image loop in interactive mode. + + Davis, Feb23,1988 + +apphot$ + 1. All the next now print out a short help page at startup time if they + are run in interactive mode. + + 2. I changed the task termination sequence. q from inside the cursor + loop calls up a verification sequence, return goes back into the cursor + loop, n exits the cursor loop and asks for the next image, q quits the + task and w quits the task and writes to the pset parameter files. + + 3. I have added the bell character to the end of all warning messages. + More specific error messages were added to tell people that they are + at the end of a coordinate lists etc. + + Davis, Feb18,1988 + +apphot$ + I switched the exposure and itime parameters from the photpars and + polypars psets to the datapars pset where they more properly belong. + + Davis, Feb9, 1988 + +apphot$ + If salgorithm = constant then the algorithm which computes the magnitude + errors will try to use the value of the sigma parameter to estimate the + random noise inside the aperture. If sigma is INDEFR it will use only the + poisson statistics of the star. + + Davis, Feb 6, 1988 + +apphot$ + Moved the pfeature parameter from centerpars and placed it in datapars + where it logically belongs. + + Corrected a radprof error in which the extracted pixel array was being + call out of bounds even when it wasn't. + + Polyphot was centering on the cursor position even when no polygon + had been defined. + + Davis, Feb 5, 1988 + +apphot$radprof/,apphot$apselect/ + Fixed a minor bug in apselect. If string parameters were exactly equal + to their formatted lengths then a single extra character would get + printed at the end of each selected field. This happened for example + when the photometry parameter was out of bounds. + + In the radprof task the sky subtracted sums were being printed out + instead of the total sums. The mangnitudes were being computed + correctly. + + Davis, Feb 2, 1988 + +apphot$apselect/ + Made extensive changes to the keyword and units string maintenance + facilities, mostly to make the package easier to maintain. + + Changed the pfeature keyword to emission which makes more sense. + + Davis, Jan 25, 1988 + +apphot$t_apselect.x + Corrected a bug in the apselect program in which the package would + crash if the fields string was set to NULL. I included a check for + the null string in the t_apselect.x procedure. + + Davis, Jan 20, 1988 + +apphot$ + I made the task lintran part of the apphot package. This allows the + user to manipulate the coordinate lists. + + Davis, Jan 20, 1988 + +apphot$polyphot/pyprint + I corrected an error in the format string for the polyphot magnitude + error which was shifting the number over 2 columns. + + Davis, Jan 9, 1988 + +apphot$daofind/apfind.x + A bug in the way daofind computed the convolution kernel for very + small kernels was discovered and corrected. The kernel is supposed to + be defined for all pixels < 2.0 pixels from the center. For small + kernels these elements were being left at zero. IN most cases this + causes no problems except for the fact that the sharpness parameter + was lower than seen from daofind and that the nomalization for the + magnitudes is different. Workarounds are to increase nsigma from the + default of 1.5. + + Davis, Jan 6, 1988 + +apphot$polyphot/polyfit.x + The itime normalization was not working correctly in the polyphot + task. The time was being picked up correctly but the zero-point + correction was not being made to the magnitude. + + Davis, Dec 31, 1987 + +apphot$polyphot/pybphot.x + Davis, Dec 30, 1987 + I fixed a bug in the polyphot batch mode processing routine. An + "illegal file descriptor" error was occurring when polyphot was run + in batch mode with a null coordinate file list and a polygons list. + +apphot$ + I continued the clean up of apphot output files. Some of these + bugs could cause problems for potential users of apselect. + Changed the units string for CERROR, SERROR, PERROR and RERROR to + "cerrors", "serrors", "rerrors" and "perrors" from "cerror", + "serror", "perror" and "rerror" respectively to make things consistent + with the other tasks. + + I changed to polyphot units string for ZMAGNITUDE and EXPOSURE to + "zeropoint" and "keyword" respectively for consistency with the phot + bug. + + Fixed a bug in the polyphot output file where a # was missing in front + of the line beginning with XCENTER. + + Fixed a bug in the output of fitpsf with function = radgauss where + the SIGMA keyword was used for two different quantities and only the + first one was being output. + + I changed the order of the output table headers from for example + #N#N#N #U#U#U and #F#F#F to #N#U#F #N#U#F and #N#U#F. I rechecked + apselect on all this. + + Davis, Dec 22, 1987 + +apphot$ + I added a comment about the definition of box in the fitpsf parameter + file. + + Changed the output format of the center task slightly. The units for + HOST are now "computer". Similarly the units string for GAIN and + CCDREAD are now "keyword" and "keyword". These changes will affect + all tasks in the apphot package which use the datapars parameter set. + + Changed the units string for SALGORITHM to "algorithm". I also corrected + an error in the COORDS keyword by changing it from CCORDS to COORDS. + I added an s to the ERROR units string, changing it from error to + errors. + + I corrected a bug in the output file for the wphot task. The record + names, units and formats were not being written to the output file. + The problem was that the task name in the batch program had not + been changed from ophot to wphot. See also that the task statement + was incorrect. + + Davis, Dec 21, 1987 + +apphot$ + I changed the default mode for the binary version of the plotfile from + NEW_FILE to append. This avoids annoying cannot open plotfile + information when phot is run many times. The user must be aware + however that very long plot files can be generated. The affected + tasks are center, fitsky, phot, wphot, and radprof. + + Davis, Dec 21, 1987 + +apphot$apselect/apselect.x + I installed the new apselect in apphot. In the process I fixed the last + memory allocation bug which only showed up in the output of the radprof + program where the records were unusually long. + + Davis, Dec 21, 1987 + +apphot$radprof/apprprof.x + I fixed some minor bugs in the output format of radprof which were + causing apselect errors. First the records PRADIUS, INTENSITY, INTENSITY + should read PRADIUS, INTENSITY and TINTENSITY. The total intensity + record was never being read. I added a trailing slash at the end of the + magnitude record to indicate that the record continued on to include + the radial profile. If the radial profile was long > 20 records a + segmentation violation would occur as the program was not reallocating + extra memory correctly. + + Davis, Dec 21, 1987 + +apphot$radprof/aprpinit.x + Radprof was not reading multiple appertures from the photpars parameter + file correctly. The problem was that the napert and weight arguments + were reversed in the call to ap_photsetup making napert always equal + to 1. + + Davis, Dec 15, 1987 + +apphot$apselect/ + Array subscripts in the apselect task were not being handled correctly + on the sun machines. The problem was in the call to the stridx routine. + A character constant was being placed in the first argument which is + interpreted as an integer. This wa ok on Vax machines with their reverse + byte order but did not work on the Suns. I set up some character + constants and taht removed the problem. + + Arrays and array elements were not always being handled correctly by the + expression parser. In fact arrays are curently illegal in expression. + The program will now abort with a more informative error message if + it detects an array in an expression. Array elements are permitted + however. + + I added some missing mfree statements which were causing random + segmentation violation errors from time to time. + + Finally I made some changes for the sake of efficiency. For example + I call the routine apchoose only once instead of once for each record + in the output file. + + Davis, Dec 15, 1987 + +apphot$apphot.hd + Changed the name of the wphot help page from ophot.hlp to wphot.hlp + and the same of the source code file from t_ophot.x to t_wphot.x. + Ophot was the historical name of this package. + + Corrected an error in the installation guide instructions on installing + the help database. The help apphot command was not functioning + correctly.
