(12/5/11, Valdes) + +catquery/cqdef.x +catquery/cqquery.x +catquery/cqimquery.x + Modified the URL access to use the new url_get() procedure as a + compile-time option. This allows access to servers that may + redirect the URL or return some other http error. (10/5/11, MJF) + +fixpix/ytpmmap.x + The world matching was not right. It may still have bugs but the + discovered problem has been fixed. (3/3/11, Valdes) + +======= +2.15.1a +======= + +pkg/xtools/icfit/icdeviant.gx + There were two bugs related to growing. First, the logic was wrong. + Second, in one place the grow parameter was treated as being in pixels + and in another as being in user coordinate units. + (6/28/10, Valdes) + +pkg/xtools/xtextns.x + Pixel list masks were not recognized as images. + (2/13/09, Valdes) + +lib/pkg/rmsorted.h +pkg/xtools/rmmed.x +pkg/xtools/rmsorted.x + Modified the running median library to allow running minimum and + running maximum. An argument addition required a change in the + runmed task but there was no functional change. + (10/29/08, Valdes) + +xtextns.x + 1. The wrong ranges package was used for the extension versions. Calling the correct one requires extension versions to be positive integers. + 2. The extension version was not being matched correctly. This may + have happened when switching to using the mef library. + (8/25/08, Valdes) + +fixpix/ytpmmap.x + The inefficiencies in evaluating the WCS were addressed. + (3/18/08, Valdes) + +fixpix/ytpmmap.x + Fixed a couple of bugs that could result in a floating point exception. + (3/17/08, Valdes) + +rmsorted.x + This routine was modified, including adding and argument, to + support the clipping of bright values. + (2/29/08, Valdes) + +rmmed.x + This general package of running median routines was moved from + images$imfilter/src. It was enhanced by allowing clipping of + bright sources. This means a new argument, nclip, is required. + (2/29/08, Valdes) + +fixpix/ytpmmap.x + 1. Any number of '^' characters can be in the name at any point to + invert or uninvert a mask. This is needed if an application wants + to invert the mask specified by the user which may also include '^'. + This also allows strings like !^foo or ^!foo. + 2. The pmmatch variable may not be "world N" where N is the maximum + input mask value to be preserved in the output mask. This value + is used to optimize the internal bit array to the smallest it + can be consistent with the desired value. A value of "world" + is equivalent to "world 1". + (2/5/08, Valdes) + +xtbitarray.x + Generalized to support different number of bits per element. The + value is now set by specifying a maximum value. All values greater + than the maximum are set to the maximum. (2/5/08, valdes) + +inlfit/innlinit.gx + Removed an extra argument from the nlfree$t() call (1/16/08, MJF) + +fixpix/ytpmmap.x + 1. A feature to match masks in world coordinates, but only as a + boolean mask, was added. + 2. The way the pixel mask matching is selected was generalized. + The matching type is specified as a string with values + "logical", "physical", "world", or "offset". An application + may also specify an environment variable which the user may + use to specify the type. If the application specifies one of + the types then the environment variable "pmmatch" may be used + to override the application. + (1/9/08, Valdes) + +xtbitarray.x + +mkpkg + This provides a package for creating an in-memory 2D bit array. + This can be used for large boolean masks with random access. It + is being added for use with pixel mask matching in world coordinates. + (1/9/08, Valdes) + +===== +V2.14 +===== + +fixpix/setfp.x + + This routine transforms the input mask values into the output mask + values. It allows the input mask to have two classes of bad pixels; + those which are interpolated and those which are not. + +fixpix/ytpmmap.x + Adds a procedure yt_mappm and internal argument to allow control of + the WCS matching of masks to images. The earlier versions always + matched masks using the physical coordinate system. Applications can + the new procedure to have some control over this. + (11/26/07, Valdes) + +t_txtcompile.x + +txtcompile + +mkpkg + This application compiles a text file into an SPP procedure that + can be called by the xt_txtopen procedure. The application is intended + to be used as a host preprocessing command in mkpkg files to support + things like host callable applications (e.g. see syshost). The + code is in xtools for savvy developers awaiting full integration. + (11/26/07, Valdes) + +xttxtfio.x + +mkpkg + The routines xt_txtopen and xt_txtclose follow the usual FIO + interface. They allow calling a procedure that sets a string file as + if it was a read-only file. (See the t_txtcompile.x procedure for a + way to create a procedure from a text file.) The file name for this + special case of a procedure uses the syntax "proc:NNNNNN" where NNNNNN + is the value returned by locpr. The application would construct this + name for the procedure it declares as extern. The intended purpose is + to allow building in configuration files, including a parameter file, + into a host callable executable where unsatisfied parameter values + default to a built-in file rather than issuing a prompt (see syshost). + When called with an actual file normal read-only FIO is used. + (11/26/07, Valdes) + +syshost.x + +mkpkg + This routine may be used by an application to set default + parameter values when the executable is called directly by the + host. The routine provides three files to search in order; two + keyword=value files and a par file. These files, primarily the + par file, may be encoded as compiled procedures (see txtcompile + and xt_txtopen/xt_txtclose) so that the binary can be distributed + without any configuration files. (11/26/07, Valdes) + +xtextns.x + Further restructuring of these routines to support binary tables. This + makes use the mef routines. (11/26/07, Valdes) + +===== +V2.13 +===== + +catquery/cqgfields.x + The documentation says that the offset field in the catalog description + file for simple text is the field number. However, the implementation + did not work this way. The changes makes the catalog parsing work as + described. (7/17/07, Valdes) + +xtextns.x + +doc/xtextns.hlp + +doc/xtools.hd +mkpkg + Routines for expanding MEF image extensions. The first version of + this functionality was developed for proto.imextensions and then + expanded for mscred.mscextensions. Since then these routines have + been used in other tasks and so these are now being escalated to + generic xtools routines. (3/20/07, Valdes) + +xtmaskname.x +doc/xtmaskname.hlp + +doc/xtools.hd + The case where masktype=pl and the input name doesn't have a .pl + extension was wrong. (3/19/07, Valdes) + +fixpix/ytfixpix.x + + This version uses an internal copy of the input mask rather than + modifying the input mask. (3/19/07, Valdes) + +fixpix/xtpmmap.x +fixpix/ytpmmap.x + +fixpix/mkpkg +doc/xtpmmap.hlp + +doc/xtools.hd + 1. Uses xt_maskname to handle mask names. + 2. Minor bug fixes. + 3. The xt_ and yt_ versions are the same but the yt_version is + present to allow external packages to check for the presence + of ytpmmap.x and if not present use their own copy of the file. + This allows these packages to be compiled with earlier versions. + Eventually the yt versions should be obsoleted. + (3/19/07, Valdes) + +xtargs.x + +mkpkg + Simple interface to parse an argument string consisting of a list + of whitespace separated keyword=value pairs. (8/31/05, Valdes) + +======= +V2.12.3 +======= + +rmsorted.x +lib$pkg/rmsorted.h + This implements a sorted running median algorithm. + (5/12/05, Valdes) + +rmturlach.x + This implements the Turlach running median algorithm from the R package. + (5/12/05, Valdes) + +xtsample.gx + Utility to get a sample of pixels from an image. (5/6/05, Valdes) + +xtstat.gx + Utility to compute a mean, sigma, median, and mode. This is commonly + used with xt_sample. (5/6/05, Valdes) + +fixpix/xtfp.x + Wrong fix was made. (1/4/05, Valdes) + +fixpix/xtfp.x + For reasons I can't understand, the column interpolation was broken. + A loop over the columns was using ncols=FP_NCOLS, the number of bad pixels + across columns, instead of nc=IM_LEN(im,1), the number of columns in + the image. + (6/22/04, Valdes) + +numrecipes.x + Added LU decomposition. (6/18/04, 2004) + +fixpix/xtpmmap.x + 1. The routines now allow selecting whether to match masks in physical + coordinates or logical coordinates. When matching in logical + coordinates this simply means extending or trimming the mask if + the sizes are not the same. + 2. Added a new routine xt_mappm which is now the prefered routine + that allows selecting the matching type. The previous xt_pmmap + could not be changed since it used by various tasks. + (6/18/04, Valdes) + +xtmasknames.x + Added routines that hand pixel mask names. This is fairly sophisticated + in dealing with whether or not the user specifies file extensions, + image extensions, and flags. It will produced masks in FITS extensions + by default. (6/16/04, Valdes) + +======= +V2.12.2 +======= + +fixpix/xtpmmap.x + If the mask and data are offset by a fraction of a pixel it was possible + to get an out-of-bounds error. (8/14/03, Valdes) + +fixpix/xtpmmap.x + The loop over the range list in xt_match should start at 2 rather + than 1. (8/14/03, Valdes) + +fixpix/xtpmmap.x + Added some error checks to avoid a segmentation violation in xt_pmtext + when there is an error in im_pmmapo. (9/16/02, Valdes) + +fixpix/xtpmmap.x + A common case of matching a mask to an image is where the pixel sizes + are the same but there are offsets and/or different sizes. An optimized + mask matching based on using range lists and not calling mwcs was + added. (9/12/02, Valdes) + +fixpix/xtpmmap.x + Added test for a pm pointer in xt_pmmap. I can't remember why this + is was added in the version in ACE but it seems right. (9/10/02, Valdes) + +fixpix/xtpmmap.x + In the mask matching if there is no offset or sampling difference it + was returning the mask unchanged even if the sizes are not the same. + (9/10/02, Valdes) + +======= +V2.12.1 +======= + +===== +V2.12 +===== + +xtools$fixpix/xtpmmap.x + The change to IMIO for mapping bad pixel files in FITS extensions + resulted in a different error code when failing to open the file. + This code needed to be recognized by this routine in order to + continue on to try other possible formats. (2/27/02, Valdes) + +xtools$rngranges.x + Further modification for INDEF range limits. (2/4/02, Valdes) + +xtools$rngranges.x + Added missing rstr argument to 2 rng_error calls. (01/07/02, Davis) + +xtools$catquery/cqquery.x + Fixed a couple of typos in the code which detects the end of the http + header. (01/03/02, Davis) + +xtools$rngranges.x +xtools$rngranges.xBAK + + Modified rng_add to handle INDEFs better. This was the change found + in the nmisc version. There are some other differences but since the + records of why the changes were made are missing I fixed only the + immediate problem found with OBSUTIL.SPECFOCUS. + (11/14/01, Valdes) + +xtools$skywcs/doc/skdecim.hlp +xtools$skywcs/doc/skequatorial.hlp +xtools$skywcs/doc/sklltran.hlp +xtools$skywcs/doc/skultran.hlp +xtools$skywcs/doc/skywcs.hlp +xtools$catquery/doc/catquery.hlp +xtools$catquery/doc/cqsqpar.hlp +xtools$catquery/doc/cqsqparn.hlp + Fixed various formatting problems in the skywcs and catquery library + help pages. (19/09/01, Davis) + +xtools$catquery/ + Added the prototype catalog and survey access tools to the xtools package. + (27/08/01, Davis) + +xtools$fixpix/xtpmmap.x + Added missing argument to mw_ctrand calls. (6/15/01, Valdes) + +xtools$fixpix/xtpmmap.x + Fixed problems with xt_match. The new version is more robust and + correct. A bad pixel for the reference image is the maximum of all + pixels in the pixel mask which fall within the reference pixel. This + version still does not allow any relative rotations but does allow + non-integer offsets. (4/24/01, Valdes) + +xtools$fixpix/xtfixpix.x + Added a call to pm_compress to compress the pixel mask if there are + more than a certain number of edits to avoid the memory inefficiency + in plio. (2/2/01, Valdes) + +xtools$fixpix/xtpmmap.x + A mask name beginning with '^' is used to invert a mask. + (2/1/01, Valdes) + +xtools$inlfit.gx +xtools$inlfitr.x +xtools$inlfitd.x +xtools$inlrefit.gx +xtools$inlreffitr.x +xtools$inlrefitd.x + Added a check for the condition case where the number of data points + minus the number of deleted points (i.e. those with weights of 0.0) + is less than the number of fitting parameters. The previous checks did + not task into account the number of deleted points and could produce + solutions that were correct but non-physical (1/2/01, Davis) + +xtools$fixpix/xtpmmap.x + 1. The test for matching offsets was incorrect. + 2. The use of BPM was broken. + 3. There was a memory leak because imunmap does not free the pl + pointer set with im_pmmapo (also there was an imio bug in + freeing the pl pointer set with im_pmmap which has now been + fixed). A new procedure xt_pmunmap should be used whenever + xt_pmmap is used to insure any internal pointer created by + xt_match to match the mask to a reference image is freed. + (12/12/00, Valdes) + +xtools$skywcs/ + Added the sky coordinates transformation tools to the xtools package. + (10/12/00, Davis) + +========= +V2.11.3p1 +========= + +xtools/fixpix/xtpmmap.x + A mask name begining with '!' is now treated as a reference to a + header keyword. (9/4/00, Valdes) + +xtools/fixpix/xtpmmap.x + When a pixel mask (overlay or bad pixel) needed to be matched to + the data in physical coordinates the internal generation of a + new mask was being done in short integers. This would truncate + any masks with values greater than 16 bits. All uses of short + where changed to integer. (5/16/00, Valdes) + +========= +V2.11.3p1 +========= + +======= +V2.11.3 +======= + +xtools$fixpix/xtfp.gx + The formating of the verbose pixel printing was missing a couple of + blanks. (12/15/99, Valdes) + +======= +V2.11.2 +======= + +xtools$ranges/mkpkg +xtools$icfit/mkpkg +xtools$fixpix/mkpkg +xtools$mkpkg + Added missing dependencies. (10/11/99, Valdes) + +xtools$inlfit/mkpkg + Removed an uncessary file dependency from the mkpkg file. (20/9/99, Davis) + +======= +V2.11.2 +======= +xtools$fixpix/xtpmmap.x + Removed extra argument to imgl1i. (8/11/99, Valdes) + +xtools$imtools.x + fnext is a function not a subroutine. (8/11/99, Valdes) + +xtools$xtanswer.x + Fixed incorrect number of arguments in getline call. (8/11/99, Valdes) + +xtools$nlfit/inreject.x +xtools$nlfit/inrejectr.x +xtools$nlfit/inrejectd.x + Rearranged the code to remove a missing sfree statement problem + detected by spplint. (8/10/99, Davis) + +xtools$center1d.x + The step of finding a local maxima was not correct. (4/19/99, Valdes) + +xtools$fixpix/xtfp.gx + If there was no column interpolation the pixel type for the allocated + data array was not set resulting in an error during xt_fpfree. + (7/20/98, Valdes) + +xtools$%xtimnames.x + Modified extension testing code to use iki_validextn. + (7/13/98, Valdes) + +xtools$fixpix/xtfp.gx + Fixed a bug allowing out-of-bounds reference to FP_COL. + (6/6/98, Valdes) + +xtools$fixpix/xtpmmap.x + The steps to check if an image and mask have an integer relationship + (integer sampling and integer offsets) in their physical coordinate + systems could fail because real precision was not high enough + in MWCS transformation calls. Changed variables and MWCS calls + to double. (5/29/98, Valdes) + +xtools$fixpix/xtpmmap.x + The XT_PMINVERT function has a bug in using the range list. + (4/22/98, Valdes) + +xtools$fixpix/xtfixpix.h +xtools$fixpix/xtfixpix.x +xtools$fixpix/xtfp.gx + The modified data buffer returned by xt_fps$t used the imgl2$t buffer + which might be invalidated by subsequent imio activity such as + impl2$t. This was found with proto.fixpix. The routines were modified + to allocate and use a separate line buffer. Note that this only + applies to lines which are modified. If the requested line does + not have any bad pixels to fix then the input buffer is still returned. + (1/29/98, Valdes) + +xtools$fixpix/xtfp.gx + When a segment of bad pixels contains a mixture of column and line + interpolations and the first pixel is column interpolation then the + line interpolations could be wrong because interpolation coefficients are + not initialized. A second minor fix is that the column interpolation + endpoints printed in pixel listing mode could be incorrect. + (1/29/98, Valdes) + +======= +V2.11.1 +======= + +xtools$imtools.x + XT_MKIMTEMP was modified to append the same extension as the input + image when creating a temporary image name. (10/30/97, Valdes) + +xtools$ranges.x + Returned the EOLIST marker to zero since some programs rely on this. + This means that zero cannot be a range element. Added some + checks against a zero step size. (8/22/97, Valdes) + +xtools$fixpix/xtpmmap.x + There was a bug in the code which gives "Warning: PLIO: reference out + of bounds on mask". This was introduced with the changes to allow + masks and images to have different binning. (8/21/97, Valdes) + +xtools$ranges.x +xtools$doc/ranges.hlp + Now allows zero as a valid range element though the default for a + null string is still 1. (7/15/97, Valdes) + +========= +V2.11Beta +========= + +xtools$fixpix/xtpmmap.x + Improved xt_match to match when the sampling is different. + (5/21/97, Valdes) + +xtools$obsdb.x + File date was changed but the code was not changed (5/7/97, Valdes) + +xtools$dttext.x + Added the new routine dtgetd to the dttext package. (1/16/97, Davis) + +xtools$fixpix/xtpmmap.x + Fixed some bugs. (12/30/96, Valdes) + +xtools$mkpkg +xtools$fixpix/ + + Added some new tools for dealing with masks. (12/6/96, Valdes) + +xtools$center1d.x + When the width parameter is less than or equal to 1 pixel the algorithm + is supposed to return the nearest local maximum. There was a bug + such that the nearest pixel to the starting point was returned + unless that pixel is a local minimum. (10/24/96, Valdes) + +xtools$numrecipes.x + Modified the Poisson deviate routine to return zero for input + values less than or equal to zero. (10/1/96, Valdes) + +xtools$xtimnames.x + Added "fits" and "fit" as extensions. (7/30/96, Valdes) + +xtools$inlfit/ingresults.gx + Changed several INDEFR references to INDEF references so that INDEF + has the correct type (real or double) in the output .x files. + (18/7/96, Davis) + +xtools$dttext.x + The dtunmap procedure now returns if a null pointer is received. + (1/6/95, Valdes) + +xtools$center1d.x + Added a routine that allows setting some of the previously hardwired + parameters. By default the routines behave as before unless + c1d_params is called to set the parameters. (10/2/95, Valdes) + +xtools$incopy.gx + Changed 4 MEMP references to Mem$t references. The in_copyr and + in_copyd routines are not used anywhere in the system so this should + not be a problem. (8/2/95, Davis) + +xtools$rngranges.x + Added missing argument to rng_error calls. (8/2/95, Valdes) + +======= +V2.10.4 +======= + +xtools$obsdb.x + Changed the "timezone" parameter to be a double instead of an integer. + There are non-integer timezones such as India. (12/29/94, Valdes) + +xtools$numrecipes.x + The POIDEV routine can still have a problem in that the tan function + can return a very large number triggering either an overflow in + the evaluation of em or in the int truncation of em as addressed + below. A test is now made on the value of the tan function. + (9/14/94, Valdes) + +xtools$numrecipes.x + The POIDEV routine from Numerical Recipes can try to coerce a large + floating point number to an integer which can cause an exception. + If the value is 100 or greater a Gaussian deviate is now returned. + (8/11/93, Valdes) + +============ +V2.10.3 beta +============ + +xtools$center1d.x + For EMISSION features the threshold is applied as an absolute threshold + if the minimum data value is above zero and as a threshold relative to the + minimum data value if the minimum data value is below zero. Without + this change centering would fail if the data was all below zero. + (5/5/93, Valdes) + +xtools$obsdb.x + Fixed a couple of typos in comments. No code changes. (4/28/93, Valdes) + +xtools$rngranges.x + Yet another ranges package. This ranges package allows real number + ranges (including negative values) and @ lists. It is an object + oriented package using a pointer. + + RNG_OPEN -- Open a range string. Return a pointer to the ranges. + RNG_CLOSE -- Close range structure. + RNG_INDEX -- Get ith range element. Return EOF if index is out of range. + RNG_NEAREST -- Get nearest range index and value to input value. + Return the difference. + RNG_INRANGER -- Check if real value is within a range. + RNG_INRANGEI -- Check if integer value is within a range. + RNG_ELEMENTR -- Check if real value is an element. + RNG_ELEMENTI -- Check if integer value is an element. + RNG_ADD -- Add a range. + RNG_ERROR -- Set error flag and free memory. + (2/16/93, Valdes) + +xtools$center1d.x + If the initial center was more than three pixels from the true center + the interation would stop prematurely because of the dxcheck criterion. + Changed dxabs to be the full dx rather than the the limit of 1 pixel + per interation. This allows the interation to step as often as + it needs in one pixel steps until the dx estimate begins to become + small. It still preserves the checks for flipping back and forth + about the center and for a maximum number of times the dxabs + is greater than the previous minimum dxabs = dxlast. + (9/22/92, Valdes) + +======= +V2.10.2 +======= + +======= +V2.10.1 +======= + +lib$pkx/dttext.h +pkg$xtools/dttext.x + Added a new routine, dtremap, which allows keeping the database + open across multiple calls and remapping when a new database file + is specified. It is also optimized when switching back and forth + between read and append modes. The data structure was modified + to record the current database and file names for checking when + the name changes. (4/30/92, Valdes) + +pkg$xtools/obsdb.x + 1. Removed obsimcheck procedure. Did not like the defaulting + to last set observatory if OBSERVAT not found. + 2. Added obsimopen procedure. This is the procedure to call when + dealing with images. It returns flags to determine whether a + new observatory was opened and whether the observatory was + define by the image header + 3. Added a verbose obsvopen to allow tracking what the interface is + doing. + 4. These changes made in conjunction with changes to the + astutil.observatory task. + (2/4/92, Valdes) + +pkg$xtools/xtimnames.x + + Added some tools for dealing with image kernel extensions in image names. + (1/22/92, Valdes) + +pkg$xtools/inlfit/infit.gx +pkg$xtools/inlfit/infitr.x +pkg$xtools/inlfit/infitd.x + The fit status was not being updated correctly if point were + automatically rejected from the fit as opposed to being deleted. + (1/8/92, Davis) + +pkg$numrecipes.x + Added some fourier routines. Note that this is still a source only + entry and is not part of libxtools. (9/4/91, Valdes for MJF) + +pkg$numrecipes.x + mr = 0.1 * mr --> mr = max (EPSILONR, 0.1 * mr) (9/2/91, Valdes) + +pkg$xtools/inlfit/ + The interactive non-linear least squares fitting package used by PHOTCAL + was installed in XTOOLS. (8/6/91) + +pkg$obsdb.x + + New observatory database routines. (11/6/90, Valdes) + +==== +V2.9 +==== + +pkg$xtools/center1d.x + In the case that the position correction flipped back and forth about the + center no center would be found. In this case I added a check to + divide the correction factor in half. (3/13/90, Valdes) + +pkg$xtools/numrecipes.x + + Add some procedures for generating Gaussian and Possion deviates + as well as an implementation of the Levenberg-Marquardt nonlinear + chi square minimization algorithm. These routines are either + direct implementations from Numerical Recipes or based on descriptions + in that book. (10/25/89, Valdes) + +pkg$xtools/dttext.x + Commented out the diagnostic message in dtlocate. (7/19/89, Valdes) + +pkg$xtools/center1d.x +pkg$xtools/doc/center1d.hlp + If the centering width is less than or equal to 1 the nearest minima or + maxima is found. As before, a minimum width of 3 is used if + the width is between 1 and 3. (7/13/89, Valdes) + +=========== +Version 2.8 +=========== + +pkg$xtools/logfiles.x + Added these routines to open and to close a list of logfiles. + (6/2/89, Seaman) + +pkg$xtools/ranges.x + Fixed a bunch of bugs in the zero handling, the MAX_INT handling and + that made the step notation flaky. Made a comma a hard separator + between two ranges rather than mere whitespace. (6/2/89, Seaman) + +pkg$xtools/xtmksections.x + A 2D image with second dimension length of 1 is returned without + an image section from xt_mk1d and xt_mksection. (1/31/89, Valdes) + +pkg$xtools/xtsort.x + Added a double precision version of the three vector sorter, named + xt_sort3d. It required a double precision version of xts_compared. + This change was to support the utilities.curfit task, which now + sorts its input list data before fitting. (6/24/88 ShJ) + +pkg$xtools/xtsums.x + When the number of lines or columns is 1 and the line or column is the + same as a previous call and a data is null then a new vector is not read + causing uninitialized data to be returned. Added l1=0 and c1=0 to fix + problem. This problem appeared in proto.toonedspec. (2/12/88 Valdes) + +pkg$xtools/mksection.x + User specified section strings of the form "column 051" are now + converted to [51,*] instead of [051,*]. (11/9/87 Valdes) + +==== +V2.5 +==== + +pkg$xtools/center1d.x +pkg$xtools/doc/center1d.hlp + Valdes, April 2, 1987: + 1. A bug with testing the right edge of the data was fixed. This caused + FPE errors on AOS/IRAF. + 2. The centering fails if the maximum number of iterations is reached + or the changes do not continue to decrease within 3 iterations of + the last minimum change. + 3. Defined parameters replaced constants used in the code. + +pkg$xtools/center1d.x +pkg$xtools/doc/center1d.hlp + Valdes, March 5, 1987: + 1. A silent minimum of 3 is imposed on the width parameter. If there + is ever a need to allow smaller widths then the procedure can + be changed and the application relinked. + 2. The help page was modified to reflect this change. + +pkg$xtools/center1d.x + Valdes, October 29, 1986: + 1. The first use of threshold was only as a data range limit. + Now it is used to eliminate all peaks less than threshold from + the continuum. This fixes ever finding weak features less + than threshold. + +pkg$xtools/center1d.x + Valdes, August 18, 1986: + 1. Added a detection threshold parameter to CENTER1D. + +==================================== +Version 2.3 Release, August 18, 1986 +==================================== + +cogetr.x: Valdes, July 3, 1986 + 1. Error in initializing the procedure cogetr fixed. + +icfit$: Valdes, July 3, 1986 + 1. ICFIT package replaced by a new version. + +===================================== +STScI Pre-release and SUN 2.3 release +===================================== + +icfit$icgfuncs.gx: Valdes, June 18, 1986 + 1. DCVEVAL was being called in ICGFUNCS with a real argument when + selecting the nonlinear plot (key 'l'). This caused an error + on the SUN. Changed "real" to PIXEL. + +gtools$gtwindow.x: Valdes, June 11, 1986 + 1. Added new procedure gt_window. It is a cursor driven procedure + for windowing graphs using the gtools pointer. The help + page for gtools was also modified to show the windowing options. + +gtools$gtcur.x: Valdes, May 10, 1986 + 1. Took out "Confirm:" prompt so that cursor input from a file does + not cause anything to be printed. Two EOF's (carriage return or + actual EOF) or a 'q' are required to exit thus protecting the user + from an inadvertent carriage return. + +imt.x: Valdes April 29, 1986 + 1. Modified the image template package to sort wildcard expansions. + +icfit$icgfit.gx,icgfit2.x,icgcolon.x: Valdes, April 7, 1986 + 1. Fixed use of STRIDX with a character constant to STRIDXS. + 2. Fixed problem with colon usage for ":sample" and ":function" + +xtools: Valdes, March 24, 1985 + 1. Added XT_PHISTORY to put dated history string. + +pkg$xtools/imtools.x: Valdes, March 18, 1985 + 1. XT_MKIMTEMP modified to create the temporary image header in the + user current directory with the prefix "tmp". + 2. XT_DELIMTEMP modified to call IMRENAME instead of RENAME. + +From Valdes March 13, 1986: + +1. Added procedure dtgad (database get array double) to dttext tools. +It's purpose is to accomodate double precisions curve fits. + +2. Added COGETR procedures for efficient column access. A help page +is available. + +3. Added XTSUMS procedures for buffered sums (both column and line). +They are particularly useful for moving sums type of operations. A help +page is available + +4. Added help pages for COGETR and XTSUMS procedures to help database. +------ +From Valdes March 10, 1986: + +1. Added IMTREW rewind procedure to image template tools. + +2. Added IMTGIM procedure to get an image from the template by index number. +------ +From Valdes March 5, 1986: + +1. Modified dttext to allow deleting a database. +=========== +Release 2.2 +=========== +From Valdes Feb. 8, 1986: + +1. Modified XT_DELIMTEMP and DEL_IMTEMP to update the pixel header +file so that it correctly points to the header file after the header +file is renamed. +------ +From Valdes Jan. 13, 1986: + +1. Changes in DTTEXT.X: + a. Size of OS filename in DTMAP1 extended from SZ_FNAME to + SZ_PATHNAME + SZ_FNAME. + b. Database directories do not allow periods in the names when + created. +2. XTMKSECTION was computing the middle line (or column) as +len / 2 which gave zero for an image of length 1. Changed to +(len + 1) / 2. +------ +From Valdes Dec. 31, 1985: + +1. A bug in imt.x due to incorrect indexing in a string has been fixed. +------ +From Valdes Nov. 22, 1985: + +1. A new procedure XT_GIDS has been added to find identifier tokens in a +string and match the identifiers against a dictionary string. An array +of YES/NO values for each dictionary entry, up to a maximum of maxids, +is returned. This procedure is useful for parsing an option string. +It is nice because identifiers can be abbreviated and delimiters can be +anything which is not an identifier token (whitespace, commas, colons, +semicolons, etc). +----- +From Valdes Nov. 15, 1985: + +1. Added DTMAP1 to DTTEXT.X text database package. This procedure +takes a directory name as the database and stores or access text database +files in the directory under the file name key. It maps the name +"database/key" and calls DTMAP. This allows better organization of +database information into subfiles of a database rather than one massive +text file. It calls DTMAP with the database name directly if the database +name is a regular file and not a directory. Thus, it is backwards +compatible with older single file text databases. + +2. Added ISDIRECTORY. This procedure tests a virtual file name to see +if it is a directory and returns the os pathname suitable for concatentation. +The function value is the number of characters in the pathname which is +0 for a nondirectory file. +cogetr.x: Valdes, July 3, 1986 + 1.
