GEMINI (Jun2003) Gemini IRAF package v1.4 GEMINI (Jun2003) Release date: June 3, 2003 Essential bug fixes for the Gemini IRAF package v1.4 gmos.gnsskysub This task for reduction of N&S data was not included in the Gemini IRAF package v1.4, though it should have been. The task is defined in the original release. gmos.gmosaic Bug fix for handling of binned images. The separation of the chips for images binned in X was incorrect. The rotation for chip 1 and 3 was incorrect for Xbin!=Ybin. The mapping of chip 3 has also been improved. gmos$data/mgmos_bpm11.pl gmos$data/mgmos_bpm22.pl BPMs to match the revisions in gmosaic. gmos.gireduce Various fixes to make the task more stable under Linux. No changes to the functionality of the task. ----------------------------------------------------------------------------- Release date: September 20, 2002 This document describes the revisions relative to the Gemini IRAF package v1.3 PRIMARY REVISIONS: 1) Tasks for reduction of GMOS IFU data are now included in the "gmos" package. 2) A cosmic ray rejection task is included for GMOS spectra. 3) Tasks for reduction of NIRI longslit spectroscopic data are now included in the "niri" package. 4) New tasks have been added to the "oscir" package, which now serves as the prototype of the reduction software to be developed for T-ReCS and other mid-IR imagers. DETAILS OF THE REVISIONS: gmos All tasks in the "gmos" package should be unlearned prior to use in order to implement new parameters and default parameter values. gmos.gbias gmos.ggain (hidden task) gmos.gireduce gmos.gprepare gmos.gstransform gmos.gswavelength Small bug fixes and better stability. gmos.gdisplay Transparent handling of images with only one extension. gmos.gmosaic User defined interpolation type. gmos.garith The task has been retired and replaced with the generic MEF arithmetic task gemtools.gemarith gmos.gscut Distortion in the X-direction taken into account. Easier user defined X- and Y-offsets Small bug fixes and better stability. gmos.gsextract Support for sky subtraction as part of the extraction. gmos.gsflat Support for the user defined X- and Y-offsets in gscut. gmos.gsreduce User defined interpolation type. Optional call to gscrrej. gmos.gnsskysub New task for sky subtraction of Nod-and-Shuffle data taken with GMOS. gmos.gscrrej gmos.gscrmask New tasks for cosmic ray cleaning of GMOS spectroscopic data. gmos.gfapsum gmos.gfcube gmos.gfdisplay gmos.gfextract gmos.gfquick gmos.gfreduce gmos.gfresponse gmos.gfskysub gmos.gftransform New tasks for reduction of GMOS IFU data. A description of the typical IFU reductions is included as the task "gmosinfoifu". Example reductions of IFU data are included in "gmosexamples". gmos.mostools.stsdas2objt Small bug fixes. Support for Flamingos-I. niri All tasks in the "niri" package should be unlearned prior to use in order to implement new parameters and default parameter values. niri.nprepare Handling of regions-of-interests added. niri.niflat Write BPM as a separate file. niri.nireduce niri.nifastsky niri.nisky Smaller bug fixes and optimizing. niri.nsappwave niri.nsextract niri.nsflat niri.nsreduce niri.nssdist niri.nstransform niri.nswavelength New tasks for reduction of NIRI spectroscopic data. See also "niriinfo". An example reduction has been included in "niriexamples". oscir.obackground oscir.oflat oscir.ohead oscir.oreduce oscir.oview The "oscir" package have been extended to serve as a proto-type for the reduction software for T-ReCS and other mid-IR imagers. gemtools.imcoadd Support for use of the header WCS for defining the transformations. Support for use of instrument offsets in the image headers for defining the transformations. Automatic selection of bad pixel file. Smaller bug fixes. gemtools.gemarith New task. Generic arithmetic task for MEF files. Replaces gmos.garith. gemtools.gemoffsetlist New task for splitting images lists based on offsets in space or time. Used extensively by the tasks in the "niri" package. gemtools.gemlogname (hidden task) gemtools.gemvsample (hidden task) Generic tasks for support of various parameter checking have been added to the "gemtools" package.
