Hello,

I'm learning how to write scripts, and I
can't get the script below to actually
prompt me for the "image" parameter.
This is the error code I get:

the ELLIPSE task. I'm trying to

Hi,

I'm trying to get a script to work, but
when it gets to the part where "ccdproc"
trims the biassec and performs the
"zerocor", the logfile starts growing
like crazy (it goes up to 4Gbs until
IRAF stops and says it can't open
logfile) while some tem...

Is there something similar for implot?

I tried from the implot help page:
