This patch should be unpacked on top of an already existing
Gemini IRAF package v1.7.  

This patch contains the following files:

gmos/giflat.cl
gmos/gifringe.cl
niri/nireduce.cl

To install:

[1] Unzip the file

	% gunzip gemini_v17_patch1.tar.gz

[2] Log into the CL from the IRAF account and unpack the archive file.  Change
    directories to the GEMINI root directory and user 'rtar':

	cl> cd gemini
	cl> softools
	cl> rtar -xrf <path>/gemini_v17_patch1.tar

    where <path> is the relative path from /iraf/extern/gemini to the 
    downloaded file.

    You can also unpack the file gemini_v17_patch1.tar from UNIX

	% cd /iraf/extern/gemini
	% tar xvf <path>/gemini_v17_patch1.tar


This patch contains the following bug fixes:

gmos.giflat - Better handling when the number of input files is low and 
	conflicting with the IMCOMBINE rejection parameters.

gmos.giflat
gmos.gifringe - Fix typo in the definition of the default 'statsec' and 
	'normsec' for data binned 4 by 4.

niri.reduce - The version shipped with v1.7 had a typo that would make
	the task invariably crash when fl_autosky=no.  This is now fixed.
	Also, when it needs to be, the fl_autosky parameter is now reset
	internally only; previous versions were mistakenly updating the 
	value in the uparm directory.
