typo fix for daophot.psfStarted by:Jason Quinn, 11/24/2007 05:09AM
The DAOPHOT psf task has a typo in its
parameters. There's a missing period.
Check the epar for the pstfile
parameter. It is

"Input psf star list(s) (default:
image.pst?)"

when it should be

"Input psf star list(s) (default:
image.pst.?)"

Hey,

Sometimes IRAF asks something like:

(no|yes|NO|YES) (yes):

What is the difference between no and
