Discussions have been underway for a while within NOAO regarding how best to balance the needs of internal projects, the iraf.net activities, and new projects. The result is a mutual collaboration in which IRAF development is resuming within NOAO on a modest scale, and the community support and development activities here will be encouraged and supported to some extent for those NOAO employees supporting this site (i.e. some work on this site is now/again part of our day-job).

It has been a while since the last V2.13 release, the reason can now be made clear: The effort has been going into an official V2.14 release from NOAO. This will additionally include a number of new external packages and other software that will be demonstrated at ADASS next month, and will be released in the very near future.

Update 10/23/07:The V2.14 release has been pushed back until after the release of OSX 10.5 (Leopard) so we can fix any problems that may come up.
Update 10/30/07:Preliminary tests indicate that the current IRAF binaries will work fine under Leopard. More detailed testing to be posted to the IRAFNet forum.

Code Snippets The ASTCAT package provides tools to get catalogs from web sites that support HTTP/Get URLs which return a text table. It is challenge to discover these sites and keep the the ASTCAT database up-to-date. Two important catalogs are the 2MASS point source catalog and the USNO-B1 catalog.

Buglog #559 -- TRANSFORM

Bug Logs NUMBER: 559
MODULE: longslit.transform
SYSTEM: -V2.12.3
DATE: Tue Aug 7 10:39:13 MST 2007
FROM: valdes

BUG: When using log resampling (xlog=yes or ylog=yes) it is possible to get a segmentation error. This is caused by taking the log and anti-log of coordinates and not getting back exactly the same value due to real precision problems. This process caused an attempt to go outside the valid range of the interpolator. This may be a rare problem but if it does happen one may be able to use the x1, x2, y1, y2 values to work around the problem. The workaround for a future release is to use double precision and to impose range limits on data passed to the interpolator.

STATUS: Fixed for the next release.

It's been on my list for a while now, but I finally got around to creating several new forums for the site: The Sources forum is to allow users to post small scripts or announcements of software that may be of interest to other users. A new Job Board category includes forums for users to post Open Positions that may be of interest to this group, or Resumes if you're looking for a position.

We may still want to create other means of handling these, but for now we'll see how much interest there is with this fairly simple scheme. If you have a script, know of a job opening, or have a suggestion for other groups, please post.

Buglog #558 -- MSCIMAGE

Bug Logs NUMBER: 558
MODULE: mscimage
SYSTEM: all release up to date
DATE: Fri Mar 30 11:04:18 MST 2007
FROM: valdes

BUG: MSCIMAGE defines the resampled output world coordinate system (WCS) using a reference image WCS. If this reference image has a ZPN projection an error will occur. This is because when the output WCS is set the ZPN projection is inherited from the reference image but MSCIMAGE does correctly setup the output ZPN projection from the reference image. So one must use a reference image with another projection such as TAN.

VO News Hot-wiring the Transient Universe: A Joint VOEvent & HTN Workshop will be held in Tucson, AZ on June 4-7, 2007. Registration for this workshop is now open at the conference web site: http://www.cacr.caltech.edu/hotwired/. This workshop aims to bring together developers and users of the HTN (Heterogeneous Telescope Network) Consortium and the VOEvent (transient alter notification protocol) Working Group to discuss technology, data fusion, and design of systems for the detectiona nd rapid follow-up of celestial transient events. Anybody interested in time domain or transient follow-up astronomy is encouraged to participate, not just members of the current VOEvent working group or HTN consortium. The workshop will take a global perspective from the point of view of the astronomical observing system at all apertures and wavelengths with both robotic and human mediated, real and virtual, telescopes and instruments.

Details and links (and a rather unique astronomy conference poster) available on the workshop website.

MODULE: splot
SYSTEM: -V2.13beta
DATE: Mon Dec 4 15:29:44 MST 2006
FROM: valdes

BUG: When the dispersion function for a spectrum is log sampled, e.g. DC-FLAG=1, and there is also a logical/physical pixel offset, i.e. LTV1 is not zero, then writing out a new spectrum with the 'i' key the results in a wrong WCS. There is no workaround.
STATUS: Fixed for a future release.
