Hi!

I have some ascii files in micron units.

and when I plotted them with splot I
realized that it assumed that the unit

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

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 ...

xgterm on Mac PPCStarted by:gudehus, 03/03/2008 09:04PM
Hello,

I downloaded your precompiled binary of
xgterm and tried it on my Mac PPC
running system 10.4.11. While I can
display a plot with it, I can't do any
cursor readback from it. Can you fix
this, maybe by recompiling on system
10.4.11?
