lprint dump to ps file?Started by:cbender, 02/08/2008 05:30PM
Hi -

I'm running iraf 2.12.2a under RHEL5.

Is there a way to get lprint to dump to
a postscript file instead of a printer
(similar to the ':.snap psdump'
functionality for graphics devices)?

Currently, lprint will print just fine
to my default prin...

Question on "ccdproc"Started by:hanin, 01/25/2008 06:47AM
Hello,

I have CCD images with overscan region.
When I use ccdproc, IRAF subtracted my
images with overscan region and bias
images. My question is, since the "bias"
is already inside (embedded in) the
"overscan", isn't it redundant to
subtract the bias ...
