Q:	How do I make a postscript file from the SPECPLOT?

A:	
	When you have the graph you want type one of the following

	    :.snap eps
	    :.snap epsl
	    :.snap psdump

	The first two produce a file sgiXXXXXX.eps in your working
	directory and the last produces a file irafdmpXXXXX.ps in /tmp.
	Because of buffering you might need to type ".gflush" from the
	cursor mode or "gflush" from the CL command line.  The two EPS
	files are in portrait and landscape.  You would probably want to
	rename the files so you remember what they are.

	Note that postscript in IRAF is black and white only.  To get color
	postscript see

	    http://iraf.noao.edu/iraf/web/faq/FAQsec08.html#8005

	Another task to call your attention to is "igi" in the
	tables.tbplot package.  This is a Mongo-like graphics language
	interpreter that understands IRAF files.  While you need to learn
	the language it is what I use if I really need complex graphics
	with lots of labels and spectra.  It is convenient because you can
	keep the commands in a text file.  If you are happy with SPECPLOT
	for what you are doing then this would be overkill.
