Gemini to support AstroConda in place of Ureka later this year
April 29, 2016

  • We hope to complete integration and testing of Gemini's data reduction software under AstroConda by around mid year. Until then, we continue to recommend using it under Ureka 1.5.1/1.5.2 -- see this announcement.

Gemini IRAF 1.13.1 Released
December 7, 2015

  • A new version of the Gemini IRAF package (v1.13.1) has been released. This version is recommended for processing any GMOS-S Hamamatsu CCD data but is required to reduce GMOS-S Hamamatsu CCD data obtained after the August 2015 work on the instrument. Updated configuration files and examples are included. The updates on the package are mostly contained within the gmos package.

    This version of the package is NOT distributed in Ureka. It is 100% compatible however, it simply needs to be installed separately. See the instructions in gemini_readme.txt (distributed with the package.)

Gemini IRAF 1.13 available in recent Ureka 1.5.1 release
April 9, 2015

  • Version 1.13 of the Gemini IRAF package is now available in the latest version of Ureka, 1.5.1, released last month (http://ssb.stsci.edu/ureka). Linux users who need to reduce NIFS data (or use the task gemcube) are advised that the Red Hat Enterprise 6 build has sometimes been observed to produce non-optimally-aligned spatial grids when creating data cubes with gemcube/nifcube, a limitation that you can avoid by retrieving the Red Hat Enterprise 5 build (see "Installing Ureka Manually" in the documentation), whether or not you have a newer OS. The advantage of the RHE 6 build is that it also includes the Numba optimizing Python compiler.

Yosemite Compatibility
November 19, 2014

  • Gemini IRAF and Ureka 1.4.1.2 appears to be compatible with Mac OS X 10.10 Yosemite. If upgrading, to Yosemite, you will need to reinstall Xquartz as the upgrade wipes /usr/X11. Re-installing Xquartz solved all the X11 problems we encountered during testing.

SAOImage DS9 v7.2 Compatibility
June 12, 2013

  • The Gemini IRAF package is not compatible with DS9 v7.2, due to recently discovered bugs. Users requiring IRAF / the Gemini IRAF package should NOT upgrade to DS9 v7.2 at this time. SAOImage DS9 recommend that IRAF users instead use DS9 v7.1.

IRAF v2.16 Compatibility
September 12, 2012 (updated November 14, 2014)

  • The Gemini IRAF package is not compatible with IRAF v2.16 as distributed by NOAO. Users requiring the Gemini IRAF package and IRAF v2.16 should install Ureka which contains a patched version of IRAF v2.16 that is compatible.
