I have developed a number of IDLbased routines for reducing IFU data from GMOS, NIFS, and other instruments. I have recently put these together into a package called IFSRED:
https://github.com/drupke/ifsred
This distribution contains a file (EXAMPLE.txt) that is a cookbook for reducing GMOS IFU data using the GEMINI IRAF package and these IDL routines.
IFSRED is a generalpurpose library for reducing data from integral field spectrographs (IFSs). For a general IFS data cube, IFSRED contains routines to do the following:
– find and apply a zeropoint shift in a wavelength solution on a
spaxelbyspaxel basis, using sky lines
– find the spatial coordinates of a flux peak
– empirically correct for differential atmospheric refraction
– mosaic dithered exposures
– (integer) rebin
– apply a telluric correction
IFSRED also contains a skysubtraction routine designed specifically
to deal with GMOS data; however, this can be easily modified for any
instrument.
IFSRED contains some GMOSspecific software:
– Dropin replacements for GFEXTRACT, GFTRANSFORM, GMOSAIC, and
GSCALIBRATE in the v1.12 release of the Gemini IRAF package. These
permit the propagation of a variance plane.
– A routine to create a map of the GMOS image plane prior to
resampling from hexagonal to square pixels.
Please reply to this post or drop me an email (gmail: drupke) if you find that this software works well for you, or if you find problems with it.
