Problems with multidrizzle

Karen O’Neil wrote on Jun 23, 2006

We have pyraf Revision 2.12.2a, STSDAS Version 3.5, and DITHER Version 2.2
installed on our redhat machines here. It seems to work fine for most things,
but when I try to run multidrizzle I get an error. Could you please tell me
what might be wrong with either our installation, or what I am doing? the
output from multidirzzle is below.

thanks,

Karen O'Neil

I think the error is in the last line, i.e.

KeyError: "Undefined environment variable `crrefer'"

The 'crrefer' is a logical directory used for reference data (e.g. I know it is used for SYNPHOT) and should be defined in the hlib$extern.pkg file along with the STSDAS declaration.

I'll admit total ignorance about MULTIDRIZZLE so you might also ask the STScI Help Desk at help@stsci.edu since this is their software. Hope this helps.

Cheers,
-Mike

As I just stumbled upon this thread, searching for that error message, I ll post this, even though it's been more than a yeare since the original question:

What caused the problem for me was, that I had forgotten to

"set uref=/somewhere/folder_where_the_calibration_images_are/"

prior to calling multidrizzle (the terminating "/" is important).
