feature to view a radial plot of my

Hi, Mike et al---

This problem may be well known to
everyone, but I've found myself using

an image in ds9, it fails to pick up the
WCS. But, if I load the same fits file

Hi,

Can one tell me if the

lines or not? I have found not much
about it in the help.

The IRAF ThAr line list does not have an
"intensity" column, which would tell
what lines have high counts so therefore
