(8/28/91, Valdes) + +longslit$transform/igsfit/igssolve.x + The case of a single trace along x handled by igs_solve3 was using the + yorder instead of the xorder in one place. (7/11/91, Valdes) + +longslit$transform/t_transform.x + The interative inversion was made more stable by using a fudge factor. + This was needed to make the LONGSLIT test procedure work on HPUX. + (9/17/90, Valdes) + +longslit$identify.par +longslit$reidentify.par + Updated parameter files for the new version.

(4/7/88 Valdes) + +longslit$transform/extinction.x + Was incorrectly doing in place correction. (3/24/88 Valdes) + +longslit$ilsetbins.x + Increased bin string from SZ_LINE to 2048 chars. Some users have attempted + to define a large number of bins which fails when the string limit is + reached. (1/4/88 Valdes) + +longslit$transform/fluxcalib.x + Was incorrectly doing in place correction. (11/5/87 Valdes) + +longslit$transform/transform.x - +longslit$transform/trtransform.x - +longslit$transform/trgetsurface.x - +longslit$transform/trsftomsi.x - +longslit$transform/trsetoutput.x - +longslit$transform/t_transform.x + +longslit$doc/transform.hlp + The task TRANSFORM in the LONGSLIT package is used to + interpolate images onto a user defined coordinate system given as + surface functions U(X,Y) and V(X,Y) where (X,Y) are the + untransformed image pixel coordinates and (U,V) are the user + coordinates. The surface functions are derived from a set of measured + points using the task FITCOORDS. With Version 2.6 of IRAF + the algorithm used to invert the user coordinate surfaces, U(X,Y) + and V(X,Y) --> X(U,V) and Y(U,V), has been changed. Previously, + surfaces function of comparable order to the original surfaces were + fit to a grid of points, i.e. (U(X,Y), V(X,Y), X) and (U(X,Y), + V(X,Y), Y), with the same surface fitting routines used in FITCOORDS to + obtain the input user coordinate surfaces. This method of inversion + worked well in all cases in which reasonable distortions and + dispersions were used. It was selected because it was relatively + fast. However, it cannot be proved to work in all cases; in + one instance in which an invalid surface was used the + inversion was actually much poorer than expected. Therefore, a more + direct iterative inversion algorithm is now used. This is + guaranteed to give the correct inversion to within a set error + (0.05 of a pixel in X and Y). It is slightly slower than the previous + algorithm but it is still not as major a factor as the image + interpolation itself. + + The event which triggered this change was when a user + misidentified some arc lines. The dispersion function which was + forced to fit the misidentified lines required curvatures of + a couple of hundred angstroms over 100 pixels at a dispersion of + 10 angstroms per pixel. It was possible to do this to the user's + satisifaction with a surface function of xorder=6 and yorder=7. + TRANSFORM inverts this surface by fitting a function with the + same orders (it uses a minimum of order 6 and the order of the input + surface function). The transformed arc image was then examined + and found to have residual wavelength errors 5 times larger expected + from the residuals in the dispersion solution. With such a + large curvature in the dispersion surface function it turned out + that to maintain errors at the same level the fitting function + required orders of 12. (To determine this required a special version + of TRANSFORM and the new double precision surface fitting + routines). When the lines were correctly identified the + dispersion function had much lower curvatures and required lower orders + in the fit and gave a good transformation of the arc image. The + conclusions drawn from this event are: + + 1. An incorrect dispersion solution can appear to be correct if + the misidentified lines are at the end and a high enough order is + used. + + 2. This requires high order surface functions in FITCOORDS + and TRANSFORM. + + 3. The algorithm used in TRANSFORM in V2.5 and earlier, while + not failing, does give unexpectly large residuals in the + linearized arc spectrum in this case. A cautious user should transform + arc images and examine them. + + 4. In the future a more direct inversion algorithm is guaranteed + to give residuals in the transform consistent with the residuals in + the dispersion solution even when the dispersion function is not + realistic. + (9/14/87 Valdes) + +longslit$transform/trgetsurface.x +longslit$transform/fcfitcoords.x +longslit$transform/fcdbio.x +longslit$transform/trsftomsi.x +longslit$transform/trsetoutput.x +longslit$transform/igsfit/igsfit.x +longslit$transform/igsfit/igscolon.x +longslit$transform/igsfit/igssolve.x +longslit$transform/igsfit/igsget.x +longslit$transform/igsfit/xgs.x + + Modified routines using the GSURFIT routines to call an interface routine + which allows calling the double precision versions of these procedures + without changing the single precision data arrays (a double precision + copy is made within the interface).

This new database structure is what +is now created by IDENTIFY and REIDENTIFY. +------ +From Valdes Nov 7, 1985: + +1. The task MKSCRIPT has been made a basic system task. It is no longer +loaded in the LONGSLIT package but is always available. +------ +From Valdes Nov 1, 1985: + +1. New task MKSCRIPT has been added. It is loaded out of the IMRED.GENERIC +package. See the help page for the task and the revisions for GENERIC. + +2. Task FITCOORDS has been modified in several ways: + a. The images in a list of images can be fit separately or + combined into a single fit based on the value of the parameter + COMBINE. + b. Points delete interactively are recorded in a deletion list + and may be used in subsequent fits. + c. The last interactive plot or a default non-interactive plot + is recorded in a plotfile (if specified). The plots in the + plot file can be spool or examined after the fact. + +See the new help for this task. +------ +From Valdes Oct 22, 1985: + +1. New parameter "exposure" in FLUXCALIB. This parameter specifies the +image header keyword corresponding to the exposure time to be used in +calibrating the images. + +2. FLUXCALIB and EXTINCTION have been changed to take a list of input +images and a list of output images. The output images may be the same +as the input images. +------ +From Valdes Oct 4, 1985: + +1. Response and illumination modified to include the parameters for +low and high rejection and rejection iteration. +------ +From Valdes Oct 1, 1985: + +1. The package has been reorganized. Task extract has been moved to +a new package twodspec.echelle. The source code for identify and reidentify, +which are actually one dimensional tools, have been moved to the onedspec +package though they are still loaded with the twodspec package. + +2. New task fluxcalib flux calibrates long slit images using the flux +calibration file produced by onedspec.sensfunc. + +3. Illumination can now handle using a single illumination bin. + +4. Task revisions renamed to revs. Note that this is a temporary task. +------ +From Valdes September 25, 1985: + +1. New task setimages added. This task sets parameters in the image headers +defining the dispersion axis and, optionally, strings for the coordinate +types and coordinate units. This strings, if defined, are used in other +tasks for identifying and labeling graphs. + +2. Because the dispersion axis is now defined in the header the axis +parameter in tasks response and illumination have been removed. + +3. Task transform now adds coordinate information to the image headers. + +4. New task extinction corrects images for extinction. + +------ +From Valdes September 23, 1985: + +1. Reidentify has been significantly speeded up when tracing a 2D image +by eliminating most database accesses. +------ +From Valdes August 6, 1985: + +1. A bug in the absorption feature centering was fixed. +2. Numerous cosmetic changes in the graphics are being made. These will +be documented later. +------ +From Valdes August 1, 1985: + +1. The icfit package has been modified to allow resetting the x and +y fitting points with keys 'x' and 'y'. This is useful in identify +to reset the user coordinates directly in the fitting package. + +2. The :features command in identify now takes an (optional) file name +directing the feature information to the specified file. Without a +file the terminal is cleared and the information written to the terminal +with a pause at the end. With a file name the information is appended to +the specified file. + +3. A couple of small bugs in the handling of INDEF user coordinates in +identify have been fixed. + +4. The default pixel range in the icfit package when called from identify +is now the full image range rather than the range of points to be fit. + +5. The image section in identify is now used with :image just as it is +used for images given as arguments to the task. Explicit image sections +must be given, however, in database :read and :write because the optional +names to these commands need not be image names. +------ +From Valdes July 30, 1985: + +1. The tasks lsmap, lstrans, and reidentify have been changed so that +the user may specify a list of log files instead of just one logfile. +Now it is possible to have log output be written to the terminal +as well as a disk file. This is now the default. +------ +From Valdes July 27, 1985: + +1. The default user coordinate when marking a feature in identify +is the pixel coordinate if there is no coordinate function. + +2. When entering a user coordinate in identify after a (m)ark or +(u)ser key the coordinate typed by the user is matched against the +line list and the line list value substituted if a match is found. +Thus, for wavelengths the user only needs to enter the wavelength to +the nearest Angstrom and the decimal part will be found from the +coordinate list. + +3. Response and illumination have been modified to work along either +image axis. A new parameter "axis" has been added to select the +axis. For response the axis should be along the dispersion (default +is along the columns) and in illumination the axis is that slit position +axis (the default is along the lines). These changes in conjunction +with the new flat1d, fit1d, and background make the orientation of the +longslit images arbitrary! + +4. The values in the default parameter files for response, illumination, +identify, reidentify, lsmap, and lstrans have been changed. This will +cause user parameter files to be out of date. Sorry about that. +------ +From Valdes July 26, 1985: + +1. Background has been modified to use new fit1d task. It now does +column backgrounds without transposes and allows image sections. +------ +From Valdes July 23, 1985: + +1. Task lsrevisions has been renamed to revisions. The intent is that +each package will have a revisions task. Note that this means there may +be multiple tasks named revisions loaded at one time. Typing revisions +alone will give the revisions for the current package. To get the system +revisions type system.revisions. + +2. Background now does both line and column backgrounds. +______ +July 18, 1985: + +1. Help page for extract is available. +2. Help page for lsrevisions is available. +______ +July 17, 1985: + +1. Extract has been modified to allow interactively setting the +extraction limits for each trace. If this is not needed then answer +NO to the query. Any changes made in lower and upper remain +in effect to subsequent traces. The lower and upper limits are written +to the database. Older database tracings are still useable as before. +______ +July 16, 1985: + +1. A new task, lsrevisions, has been added to record revisions to the +beta test version of the package. + +2. A help page for identify is now available! + +3. A default one dimensional image section is available in the tasks +identify, reidentify, and extract. This allows use of two dimensional +images (without an image section) to be used without bothering with +the image section. It is also a little more general than regular image +sections in that a special format in terms of lines or columns can be given. +The default section is the "middle line". + +4. Extract has been changed to allow: + + a. Recording the traced curves. + b. Using the traced curves from one image to extract from another image. + +This is done by having three query parameters giving the name of the +image to be traced or which was previously traced, a list of input +images from which to extract, and a list of output rootnames +one for each input image. + + +.: +total 4520 +-rw-r--r-- 1 valdes iraf 1423 Sep 24 1985 airmass.x +-rw-r--r-- 1 valdes iraf 245 Oct 22 1985 fluxcalib.par +-rw-r--r-- 1 valdes iraf 659 Nov 18 1985 fitcoords.par +-rw-r--r-- 1 valdes iraf 879 Mar 13 1986 illumination.par +-rw-r--r-- 1 valdes iraf 3108 Jun 2 1986 lstools.x +-rw-r--r-- 1 valdes iraf 800 Aug 18 1986 response.par +-rw-r--r-- 1 valdes iraf 183 May 26 1987 extinction.par +-rw-r--r-- 1 valdes iraf 5297 Feb 3 1989 ilsetbins.x +-rw-r--r-- 1 valdes iraf 493 Feb 12 1993 calibrate.par +-rw-r--r-- 1 valdes iraf 950 Feb 12 1993 sensfunc.par +-rw-r--r-- 1 valdes iraf 758 Feb 12 1993 standard.par +-rw-r--r-- 1 valdes iraf 496 Feb 12 1993 longslit.par +-rw-r--r-- 1 valdes iraf 8574 May 14 1993 fluxcalib.x +-rw-r--r-- 1 valdes iraf 690 May 14 1993 getdaxis.x +-rw-r--r-- 1 valdes iraf 10216 May 14 1993 illumination.x +-rw-r--r-- 1 valdes iraf 5996 May 14 1993 extinction.x +-rw-r--r-- 1 valdes iraf 1567 Jul 21 1997 reidentify.par +drwxr-xr-x 2 valdes iraf 4096 Aug 12 1999 demos +-rw-r--r-- 1 valdes iraf 9206 Jan 7 2002 response.x +-rw-r--r-- 1 valdes iraf 171 Aug 27 2003 fceval.par +-rw-r--r-- 1 valdes iraf 30895 Aug 27 2003 Revisions +-rw-r--r-- 1 valdes iraf 212 Jun 10 14:38 x_longslit.x +-rw-r--r-- 1 valdes iraf 12252 Jun 10 14:38 x_longslit.o +-rw-rw-r-- 1 valdes iraf 17479 Jun 15 16:16 xtpmmap.x +-rw-rw-r-- 1 valdes iraf 3240 Jun 16 11:30 xtmaskname.x +-rw-r--r-- 1 valdes iraf 13080 Jun 16 11:43 xtmaskname.o +-rw-r--r-- 1 valdes iraf 46608 Jun 16 11:43 xtpmmap.o +-rw-r--r-- 1 valdes iraf 841 Jun 16 11:49 transform.par +-rw-r--r-- 1 valdes iraf 804 Jun 16 17:12 mkpkg +drwxr-xr-x 3 valdes iraf 4096 Jun 16 17:53 transform +-rw-r--r-- 1 valdes iraf 1613602 Jun 16 18:06 libpkg.a +-rwxr-xr-x 1 valdes iraf 2714998 Jun 16 18:06 xx_longslit.e +drwxrwxr-x 3 valdes iraf 4096 Jun 18 16:07 lscombine +-rw-r--r-- 1 valdes iraf 2331 Jun 18 16:25 lscombine.par +drwxr-xr-x 2 valdes iraf 4096 Jun 18 16:50 doc +-rw-r--r-- 1 valdes iraf 376 Jun 18 16:50 longslit.hd +-rw-r--r-- 1 valdes iraf 1499 Jun 18 16:51 longslit.men +-rw-r--r-- 1 valdes iraf 776 Jun 18 16:52 longslit.cl |
