cursors on IRAF. I want to use imexam as
part of a script and perform automated
processes on a series of images. Most
information talks about using "fscan" to
get the current position and store the
co-ordinates as var...

How to add/modify header keywords?Started by:le.davide, 01/05/2011 05:04AM
Hi all,
to use Galfit I need to have few
keywords in the image header (like GAIN
or ATODGAIN, RDNOISE, NCOMBINE). These
seems not to be present in the header.
How can I add them? (Or, if they are
called differently, how can I change the
keyword?).
Thanks.
