SPLOT windowStarted by:rohit, 10/04/2010 03:57PM
My SPLOT seems to have a mind of its
own. When I use the splot command to
plot a spectra, I get this small range,
like, 12 Angstroms. It is as if I am
zooming onto a small section of the
spectra. How do I change my view?

Below is the lpar of SPLOT.

I am trying to use splot to look at

There are a few things that I haven't
figured out how to do:
for example when I run:

of a single

Hi all,
I have a basic WCS on my mosaic images
which i'm trying to improve with

the images with MSCIMAGE and stack them
with MSCSTACK, following this example:

Starting ds9 from loginuser.clStarted by:FSBoyden, 08/21/2006 03:05PM
Hi All

It may sound a stupid Q, but how would
you call DS9 from the loginuser.cl. I
would like to skip the step where I have
to start DS9, and run it in the bg,
before every IRAF session. I am not that
familiar with coding in c-shell.

Thanx
