Bug Logs NUMBER: 580
MODULE: imcombine and variants
SYSTEM: -V2.15.1
DATE: Fri Apr 1 10:53:41 MST 2011
FROM: valdes

BUG:When the grow options is used with masks or partially overlapping data a segmentation could occur. This is because when data is absent (because of non-overlap) or excluded (because of mask) an identifier value was not initialized. The only workaround is to not use the grow options.

STATUS: Fixed for future patches and releases.

STATUS: This has been fixed for the next release. A patched x_onedspec.e binaries can be installed from ftp://iraf.noao.edu/iraf/v215/support//x_onedspec.e where the is either 'linux64' or 'macintel'.

MODULE: splot, scombine, fxcor, identify tasks, dispcor, disptrans
SYSTEM: v2.15-V2.15.1a (64-bit platforms only)
DATE: Tue Mar 8 21:57:38 MST 2011
FROM: fitz

BUG: The 64-bit port changes to iraf$noao/lib/smw.h improperly added a P2R() macro to the APLOW/APHIGH macro declarations. This was causing tasks with 2-D data to make an out-of-bounds request for data and leading to and error message such as
    ERROR: Pixel subscript out of bounds (spec.fits)
Normal onedspec data or use on 32-bit platforms is not affected.

STATUS: Fixed for the next release. A re-application of the v2.15.1a patch file or new installations of v2.15.1a will replace the affected binaries on 'linux64' and 'macintel' platforms.

An IRAF v2.15.1a Patch release is now available from the IRAF anonymous ftp archive at

This patch is a minor update of the IRAF v2.15.1 release for all 32- and 64-bit Linux and Mac OSX systems. It is being made available now to address the following specific issue:

  • Potential Data Corruption on 32-bit Images

In addition, several bug that were discovered in the weeks since the initial v2.15.1 patch are also fixed in this release. We apologize for asking users to install another patch so soon after a previous release, except for the discovery of another major system bug affecting all tasks we do not forsee another patch being required for at least 6 months. The version number is meant to reflect the minor changes to the system implied by this release.

Details of this patch and upgrade instructions may be found in the release announcement below.

Bug Logs NUMBER: 577
MODULE: dohydra, dofibers, doargus, do3fiber
SYSTEM: -V2.15.1
DATE: Fri Feb 11 12:30:46 MST 2011
FROM: valdes

BUG: The tasks will shorten root input image names to six characters by using the first five and last characters. Depending on the style of image names this can result in name conflicts. The reason for this shortening is no longer known so it is now considered a bug. Workarounds are to be aware of this and rename image names to avoid conflicts.

STATUS: This is fixed in the next release. The fix is to modify the file $iraf/noao/imred/src/fibers/proc.cl as shown (replace lines 125 to 129 with "extn = extn // ".ms"). If you don't have permission to make this change then copy the file to your iraf "home$" directory, edit it, load the desired package, and then override the definition of the file with "redefine proc = home$proc.cl".

    The release of the IRAF V2.15 system (featuring 64-bit platform support) is now available from NOAO. This release covers both 32- and 64-bit Linux and Mac OSX systems (Intel and PPC) and is now recommended for all users and developers. Modified sources for some 30 external packages which have been ported to 64-bit are also available from the FTP archive extern directory. Support for additional platforms and updated external package distributions will be made available in the coming weeks.

    IRAF v2.15 is now distributed as a single-file download for each supported platform. Installation is now just a matter of unpacking this single tarfile and executing the iraf install script. Similarly, v2.15 also features a new external package mechanism to automate the download and installation of packages. A full list of features and changes is detailed in the Release Notes.

    IRAF v2.15 Distribution Files:

    This release include a unified linux architecture suitable for all 32-bit Linux distributions. Similarly, the macosx architecture is now a Universal (Intel and PPC) 32-bit distribution. On 64-bit linux platforms the architecture name is linux64, the macintel architecture name now refers explicitly to 64-bit OSX (Intel). Despite the architecture name changes, older external packages can continue to be used (see the README or 64-bit Port Guide for details).

    Please contact us or post questions to the support forums with any problems or questions you may have.

Bug Logs NUMBER: 576
MODULE: imcombine
SYSTEM: V2.14
DATE: Wed Nov 17 15:20:16 MST 2010
FROM: valdes

BUG: The addition of the image names using imcmb="$I" does not work for input images with a square bracket; e.g. foo[1], foo[im1], foo[*,*]. The IMCMB value, in order to allow long filenames, is stripped of any path. For an obscure reason related to VMS directories this code failed to find a rootname.

STATUS: This has been fixed for the next release.

IRAF v2.15 to be Available for iPad

With the recent decision that jailbreaking your iDevice is legal, and how easy it now is to do, it seemed a good time to dust off the earlier IRAF iPod port and try it out on my new iPad. As before, the hard part was setting up a development environment, but since most of the work had already been done, it was pretty easy to merge the iPad port into main system as just another platform.

IRAF is now running on the iPad and will be available as part of the main v2.15 release for jailbroken iPad/iPhone/iPod Touch devices running iOS 3.1.2 or earlier. I'll post more details at the time of release, the purpose for this post is to let you know what's coming so you can hold off on iOS updates beyond 3.1.2 which will likely hinder your ability to easily jailbreak your device. If you want IRAF on your iPad, do not update your iOS just yet!! iOS4 (and indeed anything beyonf iOS 3.12) is not yet included in this announcement.

See below for more about what's working (and how well), and what you'll need to have ready to impress your friends, bosses, and to justify that year-end purchase you know you wanna make....

Update 8/14/10: DS9 now running, X11IRAF compiles but does not yet run.
