(4/6/10, MJF) + +asttools/refrac.x + A development routine for refraction correction from apparent to + observed place. As noted in the comments, this seems to be correct + to first order but I don't have complete confidence that I've done + this correctly. It would be useful to have an independent test. + (7/2/08, Valdes) + +t_rvcorrect.x + If a UT time is part of the date keyword it is used in preference to + the UT keyword. This makes use of UTMIDDLE, with the previous change, + consistent. (12/10/07, Valdes) + +t_setairmass.x + The UTMIDDLE keyword will now always be in date format. This fixes + a problem with changes of the date and insures other tasks which + use UTMIDDLE in place of DATE-OBS will used the correct time. + (12/10/07, Valdes) + +===== +V2.14 +===== + +======= +V2.12.2 +======= + +astutil.cl +t_ccdtime.x - +ccdb.x - +ccdtime.par - +mkpkg + CCDTIME was moved to the OBSUTIL package in V2.12. But the version in + ASTUTIL was retained. The change here was to have the ASTUTIL version + point to the OBSUTIL version so that there is only one source, + parameter file, and executable. (4/28/03, Valdes) + +===== +V2.12 +===== + +t_rvcorrect.x + If imupdate=no then the image is now opened READ_ONLY. Previously + the image was always opened READ_WRITE requiring the user to have + write permission on the image. (12/14/01, Valdes) + +t_setairmass.x + Previously if DATE-OBS included the UT then that time was used and + it was not possible to specify an alternate UT. Now the UT keyword + has precedence over DATE-OBS. To allow the keyword for UT to point + to DATE-OBS for the time the UT keyword may be specified in either + data/time format or as hours. + + The UTMIDDLE output option will now be written in the same format as + the keyword used for the input UT. + (9/20/01, Valdes) + +t_rvcorrect.x + Previously if DATE-OBS included the UT then that time was used and + it was not possible to specify an alternate UT. Now the UT keyword + has precedence over DATE-OBS. To allow the keyword for UT to point + to DATE-OBS for the time the UT keyword may be specified in either + data/time format or as hours. + (9/20/01, Valdes) + +pdm/pdmtheta.x + The procedure that bins the data would compute negative bins leading + to memory corruption when the input x values are not sorted. I made + a fix to this which solves the immediate problem. I didn't figure + out the code enough to know if there is any other assumption about the + input data being sorted. (2/22/01, Valdes) + +t_rvcorrect.x + Task now checks if a file specified in the "files" parameter is actually + and image and prints a warning. See buglog 477. (1/31/01, Valdes) + +pdm/TODO + + Added a TODO file for suggestions for further work. + (12/11/00, Valdes) + +setairmass.par +setairmass.hlp +t_setairmass.x +airmass.x +mkpkg + The image header keyword parameters ra, dec, equinox, st, ut, + and the scale height parameter were added to the setairmass task. In + the previous version of the task ra, dec, equinox, st and ut were + hardwired to "RA", "DEC", "EPOCH", "ST", and "UT", and the scale + parameter was hardwired to 750.0. (10/31/00, Davis) + +t_ccdtime.x +doc/ccdtime.hlp + It is now an error if time<0, time>10-000, abs(mag)>40, snr<0 or + snr>100000. (8/24/00, Valdes) + +astfunc.x + There was a typo in the opcode for CLPUT. It was 10 instead of 20. + This resulted in not branching to the I/O function evaluator and + giving a "requires 1 argument" error. + (6/29/00, Valdes) + +doc/setairmass.hlp + Made it clear that DATE-OBS means UT date. (6/21/00, Valdes) + +======== +V2.11.3p1 +======== + +t_setairmass.x + Moved erract call before imunmap to avoid an incorrect error string + (about isodate) being printed. (10/21/99, Valdes) + +astfunc.x +t_rvcorrect.x + Added missing time.h dependencies. (10/11/99, Valdes) + +asttools/mkpkg + Added missing dependency for astgalactic.x. (10/11/99, Valdes) + +t_astcalc.x + There was an extra READ_ONLY immap when processing a list of images. + Therefore when using a long list of STF format images where a file + descriptor is opened and not closed until imunmap it was possible to + run out of file descriptors. This was not a problem with imh + or fits formats. (8/31/99, Valdes) + +t_rvcorrect.x +astfunc.x + The dates in old FITS format incorrectly are adding 1900 to the year + where the 1900 is already added by the parsing routine. + (8/30/99, Valdes) + +======= +V2.11.2 +======= + +t_asthedit.x +t_astcalc.x +astfunc.x +doc/asthedit.hlp +doc/astcalc.hlp + The epoch, julday, and mst functions now take either the old or new + FITS style date strings. The time argument is optional and if it is + not specified the time from the date string is used and if neither time + is present a value of 0h is used. New internal variables $GMD, $GMT, + and $GMDT for the current time Greenwich time are defined. + (5/19/99, Valdes) + +t_rvcorrect.x +t_setairmss.x +t_setjd.x +doc/rvcorrect.hlp +doc/setairmass.hlp +doc/setjd.hlp +doc/keywpars.hlp + Converted to use dtm_decode.

No changes were required. + (5/19/99, Valdes) + +asttools/* + All routines checked for Y2K correctness. No changes were required. + The README file had the following statement added: + + Y2K: + Most routines work in Julian days or epochs. If they have an input + year it is converted to one of these forms by calling + ast_date_to_julday. This is the only routine that has a Y2K + connection. It assumes two digit years are 20th century. These + routines are Y2K correct. + + (5/19/99, Valdes) + +doc/pdm.hlp + Added a journal reference to the algorithm. (4/26/99, Valdes) + +astfunc.x + The imdel function name was incorrectly set as imde. (4/22/99, Valdes) + +doc/galactic.hlp +doc/asthedit.hlp + Fixed minor formating problem. (4/22/99, Valdes) + +doc/ccdtime.hlp + In the formula for r(sky) was pixel area term was in the wrong place. + (3/9/99, Valdes) + +t_rvcorrect.x + Improved error catching. (3/5/99, Valdes) + +t_rvcorrect.x + Added code the catch a bad DATE-OBS keyword and print an informative + error (2/21/99 MJF) + +t_ccdtime.x + For the case where SNR is very large and a time is specified the + iteration on the magnitude might not complete. The iteration is now + capped at 100 and the test for convergence is now normalized. + (11/6/98, Valdes) + +t_ccdtime.x +doc/ccdtime.hlp + 1. The calculation of exposure time given a SNR was changed from an + interative solution to an analytic solution. + 2. The times are printed to 0.01s. + 3. The photometry aperture is now the rounded-up integer with a minimum + of 9 pixels. + (9/8/98, Valdes) + +t_ccdtime.x +ccddb.x +doc/ccdtime.hlp + 1. The database keywords can now be index by reference to the telescope, + filter, and/or telescope. + 2. A new filter keyword, "extinction", was added to specify the + extinction. + 3. The extinction is now used to fixe the previous incorrect behavior + that used 1 mag/airmass extinction. The old results are preserved + by making the default extinction be 1 if missing. However the + database files should be updated to have correct extinctions. + (8/19/98, Valdes) + +rvcorrect.par + Removed the KEYPARS pset from the parameter file. The pset is + still available to the task, but it's presence interferes with + the task when used in CL mode since the 'ut' parameter is no + longer queried and the pset value is used, resulting in an + illegal number error when getting the value (4/22/98 MJF) + +t_setjd.x + The ctod function was incorrectly declared double. (3/10/98, Valdes) + +======= +V2.11.1 +======= + +pdm/pdmdelete.x + The statement "r2min = MAX_DOUBLE" was changed to "r2min=MAX_REAL" + since r2min is declared and used as real. (10/6/97, Valdes) + +===== +V2.11 +===== + +pdm/pdmtheta.x +pdm/pdmthetaran.x +pdm/t_pdm.x +doc/pdm.hlp +pdm.par + 1. The theta calculation was incorrect when there is less than 100 input + data points. In that case overlapping bins are used and the + calculation failed to account for this. + 2. Removed the debug option. + 3. Updated help including documentation of the "pluspoint" parameter. + (10/1/96, Valdes) + +t_setjd.x +setjd.hlp + Improved error checking and interpretation of the epoch keyword. + If an epoch keyword is specified and the keyword is not found + or can't be interpreted it is an error. If the epoch is an unlikely + value a warning is printed. If the epoch begins with B or J (case + insensitive) that is ok. (8/30/96, Valdes) + +rvcorrect.par +doc/rvcorrect.par + Forgot to add the keywpars pset declaration. (8/26/96 MJF) + +astfunc.x + Added btoi function "iresult = btoi (O_VALC(args[1])=='y'..." + (6/3/96, Tody) + +astradius.cl + +astradius.dat + +doc/astradius.hlp + +astutil.cl +astutil.men +astutil.hd + A new script task, ASTRADIUS, was written that is based on ASTCALC. + It finds and prints all images from an image list that have coordinates + within a specified radius of a specified coordinate. (1/24/96, Valdes) + +t_astcalc.x + +astcalc.par + +x_astutil.x +astutil.cl +astutil.men +astutil.hd +mkpkg +doc/astcalc.hlp + + A new task, ASTCALC, was written that uses a greatly enhanced syntax + from that of the original t_asthedit. It includes assignment statements, + simple conditional statements, and expressions without assignment. + Variables are implemented with a symbol table. Image, text file, + and CL parameter I/O is done with function calls in the + expression evaluator. + (1/24/96, Valdes) + +t_asthedit.x +asthedit.par +mkpkg +doc/asthedit.hlp + The task ASTHEDIT was revised to use a greatly enhanced syntax. + Internally it is significantly different but functionally it + is similar. A new parameter, update, was added to allow images + to be used which are read-only or not to be modified. The + task allows a null image list so that it can be used as a calculator. + (1/24/96, Valdes) + +astfunc.x + +astfunc.h + + The function evaluator from t_asthedit.x was extracted to a separate + file. The set of functions was increased, primarily with the + addition of I/O functions for printing, imio, fio, clio, fmtio, + and errors. These functions are organized in a subfunction + procedure. (1/24/96, Valdes) + +airmass.x +t_setairmass.x + Moved the airmass procedure from t_setairmass.x to airmass.x. + (1/23/96, Valdes) + +astutil$t_obs.x +astutil$t_asttimes.x +astutil$observatory.par + Modified to allow non-integer timezones. (12/29/94, Valdes) + +astutil$t_setjd.x + Added an extra digit to the printed output to give times to a second. + (6/4/94, Valdes) + +astutil$t_asthedit.x + Modified this to use the evvexpr package rather than the evexpr package + since the former includes double precision datatypes necessary to + maintain precision on some astronomical quantities. (4/22/94, Valdes) + +astutil$ccddb.x +astutil$doc/ccdtime.hlp + 1. The code would not work with database entries containing whitespace. + 2. The help was not correct in describing how the number of pixels used + in the photometry is calculated from the seeing FWHM. + (4/5/94, Valdes) + +astutil$t_ccdtime.x + Modified CCDTIME to use a plate scale instead of the f/ratio and to + include an airmass term. (10/23/93, Valdes) + +astutil$mkpkg +astutil$asttools/mkpkg + The ASTTOOLS routines are now an NOAO package library which can be + referenced as -lasttools. (8/19/93, Valdes) + +astutil$t_ccdtime.x + +astutil$ccddb.x + +astutil$ccdtime.x - +astutil$ccdtime.par +astutil$doc/ccdtime.hlp +astutil$astutil.men +astutil$mkpkg + Revised CCDTIME to use a telescope/filter/detector database and to + compute and print additional information. (8/16/93, Valdes) + +astutil$t_asttimes.x + 1. The times are now always printed in the proper 24 hour interval. + 2. Also the fix to asttimes.x fixes incorrect values produced around + the new year. + 3. The header parameter also suppress printing the observatory info. + (5/27/93, Valdes) + +astutil$asttools/asttimes.x + The epoch was changed from day of the year divided by 365.25 to the + precise J2000 Julian epoch definition. This also has the effect + of fixing incorrect values of JD and LMST around the new year. + (5/27/93, Valdes) + +astutil$t_rvcorrect.x +astutil$keywpars.par + +astutil$doc/keywpars.hlp + + Added a pset KEYWPARS which is a duplicate of the RV package version, + updated the RVCORRECT task to make use of this instead of using hard- + wired image header keywords. Previously it was possible that the astutil + version of RVCORRECT would compute a heliocentric correction different + from what was found by the RV package when working from image headers. + Eventually other tasks should be modified to make use of this pset. + (5/12/93, MJF) + +astutil$t_asthedit.x +astutil$asthedit.par +astutil$doc/asthedit.hlp +astutil$x_astutil.x +astutil$astutil.cl +astutil$astutil.men +astutil$astutil.hd + ASTHEDIT is a new task which edits image headers of astronomical images. + In includes functions for airmass, astronomical times, precession, etc. + (3/30/93, Valdes) + +astutil$t_rvcorrect.x + A typo in the clgstr call in the rvc_images procedure resulted in the + input observatory name being truncated at 2 characters. Instead + of TY_CHAR for the lenght of the string it needs to be SZ_FNAME. + (2/1/93, Valdes) + +======= +V2.10.2 +======= + +astutil$astutil.par +astutil$asttimes.par +astutil$rvcorrect.par +astutil$setairmass.par +astutil$setjd.par +astutil$doc/asttimes.hlp +astutil$doc/rvcorrect.hlp +astutil$doc/setairmass.hlp +astutil$doc/setjd.hlp + Observatory parameter redirected to package parameter. + (2/6/92, Valdes) + +astutil$t_rvcorrect.x +astutil$t_setairmass.x +astutil$t_setjd.x + Modified to use obsimopen.

Added additional conversions from date to JD and back from + Numerical Receipes without having to go through the epoch. + 2. Added HJD from JD without needing to go through the epoch. + (1/29/92, Valdes) + +astutil$t_setairmass.x +astutil$setairmass.par +astutil$doc/setairmass.hlp + 1. Changed the default action to update the image headers. + 2. Added an update field to the show listing. + 3. A warning is printed if show=no and update=no since this is a noop. + (11/5/91, Valdes) + +astutil$t_setairmass.x + The hour angle was slightly incorrect because universal time, from + the exposure time, was used instead of siderial time in computing the + midpoint. (8/26/91, Seaman) + +astutil$asttools/*.x + Coerced all constants with many significant digits to double precision. + (6/24/91, Valdes) + +astutil$asttools/asthjd.x + The dummy argument t was changed to lt as declared.

A new version of the observatory task based on an observatory database + using the new interface obsdb.x in xtools was added to the astutil + executable. + 2. The observatory help was revised and moved to astutil. + 3. The observatory task itself is defined in noao and was removed + from the astutil package definitions. + (11/6/90, Valdes) + +astutil$t_asttimes.x + Added a modulus operations to convert any zone to the range -12 to 12. + (9/28/90, Valdes) + +astutil$t_asttimes.x + Changed the procedure times to ast_times to avoid a name conflict in the + HPUX port. This is a better name anyway. (9/8/90, Valdes) + +astutil$asttimes.par + Removed the range limits on the zone. Zones east of Greenwich need to + be negative to obtain the correct dates. (6/15/90, Valdes) + +astutil$doc/galactic.hlp + Corrected comment about epoch of galactic coordinates.
