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

KeyError: "Undefined environment variable `crrefer'"

I think the error is in the last line, i.e.[quote:3fdcac6a17]
KeyError: "Undefined environment variable `crrefer'" [/quote:3fdcac6a17]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,

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 [b:b04b93a0cc]"set uref=/somewhere/folder_where_the_calibration_images_are/"[/b:b04b93a0cc]prior to calling multidrizzle (the terminating "/" is important).
