MODULE: cosmicrays
SYSTEM: -V2.14.1
DATE: Mon Oct 13 10:33:15 MST 2008
FROM: valdes

BUG: The message

• ERROR: PLIO: reference out of bounds on mask

occurs when the image is not 2D. This can be a conceptual problem for data which define a higher dimensionality but with length of 1; e.g. [2048,2048,1]. This is effectively a 2D image but some IRAF tasks designed for 2D images can have problems with this.
The workaround is simply to use a 2D image section:

• cosmicrays image[*,*,1]

Of course one can also convert the image to 2D with imcopy or imslice.

STATUS: No updates are currently planned and users should use the workarounds noted above.

FROM: valdes

BUG: When using avsigclip, ccdclip, or sigclip rejection around the median (mclip=yes) the resulting final median may be incorrect. This will generally only occur if unusually small low sigma values, such as lsigma=1, are used. This was due to using a wrong variable.

STATUS: Fixed for the next release.

NUMBER: 567
MODULE: apall, apedit
SYSTEM: V2.11-V2.14.1
DATE: Tue Oct 7 10:53:14 MST 2008
FROM: valdes

BUG: The :parameters and :apertures commands cause the task to exit with an error that parameter "apertures" isn't found. This problem has existed for a long time due to a missing parameter in the hidden parameter sets.

STATUS: Fixed for the next release.

A V2.14.1 Patch release of IRAF is now available from the Downloads area and from the anonymous ftp archive at iraf.noao.edu. This release adds support for FreeBSD to the PC-IRAF release, and is the first public release of the Sun/IRAF system for Sparc CPU systems. With this patch, a total of 9 platforms are now supported.

Detailed release notes are available online, or for the impatient, are in the body of the story. These notes also contain information on how to upgrade/install this patch. The V2.14.1 patch release is recommended for all users. Please post if you find any problems with the distribution or encounter a problem upgrading your system.

I officially give up. Spam registrations from public email accounts like Gmail/Yahoo/AOL/Earthlink/Hotmail are running at the rate of 40-50/day and I'm fed up with constantly clearing them out. I myself use a Gmail account for registrations like this, but when the ratio of spam to legitimate users from these domains is 500:1 or more, it's time to take drastic action.

So, from now on, registrations from the above systems will no longer be allowed for new users. If you need to register please use your university/institutional email address: Send a note to the 'admin' at iraf.net if you'd like me to change this email afterward to anonymize it, or if you have no other email account and would like me to manually register you with one of the banned domains.

BUG: The "ocolors" parameter was being used in place of the "bpcolors" parameter. There is no workaround.
STATUS: Fixed for the next release.

NUMBER: 565
MODULE: imextensions
SYSTEM: V2.13-V2.14
DATE: Mon Aug 25 16:24:33 MST 2008
FROM: valdes

BUG: Specifying an extension version or range of versions results in an integer divide by zero. This is a bug for which there is no around.
STATUS: Fixed for the next release.

NUMBER: 564
MODULE: ccdmask
SYSTEM: -V2.14.1
DATE: Fri Aug 22 09:27:06 MST 2008
FROM: valdes

BUG: The output mask from ccdmask is incorrect if the task has been run previously without starting the executable fresh. The workaround is to type "flpr ccdmask" before executing this task to force a fresh executable.

STATUS: Undiagnosed at present. Only the workaround has been defined.

NUMBER: 563
MODULE: imexpr

FROM: valdes

BUG: Literal (quoted) strings cannot be used in expressions stored in the expression database. The quotes are stripped and then the error is that an operand by that name is not found. As a warning, single quotes in the database are not interchangable with double quotes as they are on the command line. They are interpreted as character constants and something like 'abc' will be expanded to 'a bc'.

STATUS: Double quoted strings allowed in next release.

NUMBER: 562
MODULE: mscred.ccdproc
SYSTEM: V4.8
DATE: Tue Aug 12 12:19:30 MST 2008
FROM: valdes

BUG: The fix for bug number 546 was not fully correct. It works for binned data but results in an error for data which is flipped (e.g. when CCDSEC/DETSEC have a starting column greater than the ending column as in '[2048:1025,1:2048]'. The error is that the resulting CCDSEC in the processed image will be off by one. This can result is losing a column when merging multiple amps.

STATUS: Fixed for mscred V4.9.
