Hi,

I'm working on some mosaic data and
trying to do the overscan correction
interactively. Everything works fine
when I have it do this correction
silently, and the images display fine
(both with mscdisplay and one chip at a
time with display). But ...

I've just installed stsdas and tables

It seems to have installed okay. Some
things (like catfits in tables) work
fine. But when I go to use histogram on
a text file that works fine on an older

Dear IRAF support,

Is there a possibility, for a second or
multiple plot window, somewhat similar
to the midas set/grap command?
E.g. one could be used to show the cross
section of 2d spectrum (aperture
