I'm helping a friend who has had iraf
and X11IRAF installed on his Fedora
workstation; I've been told that the
person who did the installation used

Hi all,
If there are two different exposures
along two different columns for one
object, one has to process them
independently, and at last combine the
two spectra to remove cosmic rays?

If arc lines are taken independently,
for example, He/Ne/Ar ar...

The help file says I can define a 2-d
