Gemini Data Processing Software

Gemini is developing data reduction software for use with observational data obtained with the Gemini telescopes. The released version of the software is available to users and other interested parties as the Gemini IRAF package, an external package layered upon IRAF. The Gemini IRAF package currently supports data from the following instruments: GMOS-N, GMOS-S, NIFS, NIRI, GNIRS, Michelle, TReCS, OSCIR, Hokupa'a+QUIRC and Flamingos-I. Support for other facility instruments will be added as these instruments become available. The package is organized in a number of sub-packages. It contains a generic tools package, "gemtools", and instrument-specific packages, as well as more generic packages for different types of data. The raw data from the Gemini facility instruments are stored as multi-extension FITS (MEF) files. Therefore all the tasks in "gemtools" and all packages intended for processing of data from the facility instruments are capable of handling MEF files. Gemini provides only limited reduction software for visitor instruments.


ANNOUNCEMENT - IRAF 2.14
February 5, 2008

We have completed our tests of the Gemini package with IRAF 2.14 (must include the 1/14/08 critical update). We are happy to report that no major issues have been found. At this time we are confident that the Gemini package can be used with IRAF 2.14.

IMPORTANT ANNOUNCEMENT - IRAF 2.13beta2

IRAF 2.13beta2 is not a final release and is known to still contain bugs. We recommend that users upgrade to IRAF 2.14. For those who must continue using IRAF 2.13beta2, please be aware that a problem with FITCOORDS has been found. This will affect users of the Gemini package only if IRAF 2.13beta2 (or beta1) is used.

We have acquired a fixed version of the FITCOORDS code from the IRAF group. Mac Intel / IRAF 2.13beta2 users should install this unofficial patch:
fitcoords213b2-macintel.tar.gz
Installation instructions are given in:
fitcoords213b2.README
The binaries were compiled at Gemini; if you have problems with this patch please contact Gemini (see README file), not the IRAF group.
