Install problemsStarted by:chris, 07/17/2007 05:14AM
Mike,

Ran ./install -n and everything worked
fine, except I got a fail message on:

Editing Paths

Cannot find the iraf .cshrc file
Cannot find the iraf .login file

Everything else worked.... So what do I
do to fix this?

Thanks,
Chris :D

FWHM in a different direction?Started by:amoldowa, 07/16/2007 07:07PM
Hello,

I'm relatively new to IRAF, so hopefully
this question hasn't been asked a
million times!

I'm looking at star-field images from
CFHT. I have a bunch of candidate
objects that are potentially asteroids
or comets. Their long axes (along

I am looking for a way for IRAF to
determine the average FWHM per night. I
could do this by hand but if it is

If IRAF is free as in 'free beer'...why
