Due primarily to a serious bug in the V2.11.3 version of onedspec.dispcor (see notes below) we are issuing an applications patch for IRAF V2.11.3. Since we already had to put out a patch we included a few other more minor applications bug fixes as well. This patch affects the TV.IMEDIT task and the ONEDSPEC, APEXTRACT, and RV packages. No other IRAF software is affected. The patch includes new executables for the above packages, plus updates for a number of runtime and source files. There is one patch file for each target architecture (Sun sparc, Sun solaris, SGI IRIX, Redhat Linux, etc.). The runtime and source files are duplicated in each patch, so it does not matter how many patch files you install or what order they are installed in. To install the patch you need only uncompress and untar the patch file in the IRAF root directory. See the README file in each distribution directory for more detailed installation instructions. The patch files will be found in the distribution files, e.g. DUNX/patch3a-dunx.tar.Z Compaq/DEC Alpha HPUX/patch3a-hp700.tar.Z HP/UX IRIX/patch3a-irix.tar.Z SGI IRIX PCIX/patch3a/patch3a-fbsd.tar.gz FreeBSD PCIX/patch3a/patch3a-lnux.tar.gz Slackware Linux PCIX/patch3a/patch3a-rhux.tar.gz Redhat Linux 6.1 PCIX/patch3a/patch3a-rhux52.tar.gz Redhat Linux 5.2 PCIX/patch3a/patch3a-ssol.tar.gz Solaris x86 PCIX/patch3a/patch3a-suse.tar.gz SuSE Linux SSOL/patch3a-sos4.tar.Z SunOS SSOL/patch3a-ssol.tar.Z Solaris NOTE -- Patch3a is an incremental patch for the V2.11.3 release only. IRAF must already have been upgraded to V2.11.3 before the patch is installed. The existing V2.11.3 distribution files have not been modified and DO NOT include patch3a. --------------------------- Revisions Notes --------------------------------- TV.IMEDIT: A minor change was made to trap certain error conditions and quit with a meaningful message. In particular, the case where the "imdir" directory is not readable is caught. ONEDSPEC.DISPCOR: This patch fixes bugs 460 and 462. These serious bugs prevent use of the "global" option and application of the correct dispersion function from the database. The latter bug is particularly serious since an incorrect dispersion calibration can result with no indication of a problem. ONEDSPEC.SCOPY: This patch fixes bug 453 concerning incorrectly setting the coordinate system when extracting a piece of a log-linear sampled spectrum. ONEDSPEC.STANDARD, ONEDSTDS$BLACKBODY/: This task was extended to allow flux calibration against a blackbody of specified temperature and magnitude. This is done using a new calibration directory, onedstds$blackbody, which is included in the patch. ONEDSPEC: A bug was fixed that causes an error message about not being able to delete the DC-FLAG keyword. This occurs only with one dimensional spectra that just have the most basic header information such as when importing a 1D spectrum with only the FITS coordinate keywords. Spectra extracted and calibrated within IRAF do not have encounter this problem. APEXTRACT.APALL/APSUM: This patch fixes bugs 459 and 461 caused by inadvertently linking against an older version of the code. The bugs are that the "apertures" parameter is ignored during extraction and extractions to "onedspec" format produce file names with an extra sequence number. RV.FXCOR: This patch fixes bug 456 concerning a floating overflow exception which can occur with images where the DATE-OBS keyword uses the new CCYY-MM-DD date format but with no associated time information. The time is then returned as INDEF and triggers the FPE in the heliocentric correction routines. An HEDIT workaround is described in the buglog entry.
