IRAF cl scripts for Lick Observatory images
Whilst reducing gobs of images for my thesis research I've cobbled
together a few IRAF scripts that are generally useful.
Folks who have observed at
know that the conventions
used by the Lick data acquisition system differ from those used at
These show up as differences in the
header cards. The differences
make it difficult to use the automated CCD processing tasks in the
These cl scripts and databases make the job a little bit easier...
Perform the column bias (baseline) correction for Lick images.
A helper task for lickbase
Adds IMAGETYP information to Lick images to make it easier to run
ccdproc. Also adds other useful astrometric keywords. All this
from a catalog of objects provided by the user.
For purposes of using lickast I have assembled an obsdb.dat
file for IRAF. This gives the positions of the telescopes on
Mt. Hamilton to permit hour
angle and airmass calculations.
