ccdred problem

Marek42 wrote on Feb 17, 2007

So I just installed the current version of Mac OS X Intel IRAF from the download site here and I'm getting this weird problem:

ccdred> zerocombine *fits
ERROR: No images to combine
"pclip=pclip, grow=0)"
line 47: ccdred$zerocombine.cl
called as: `zerocombine (input=*fits)'

it also occurs if I use *.imh or @files with or without imh included in the file names. zerocombine is just a cl script and running combine by itself as it does seems to work fine.

I also did an unlearn on zerocombine and combine. darkcombine also shows the same issue.

I also noticed that when i start IRAF i see:
IRAFNET PC-IRAF Revision 2.13-BETA2 Wed Apr 19 21:21:13 MST 2006
This is the IRAFNET version of IRAF V2.13 supporting PC systems.

but the binary is dated from Nov 22, 2006.

Thanks!

Unless the 'ccdtype' parameter to ZEROCOMBINE is a null string, it will only combine images with the named type. The type of an image is normally stored in a 'ccdtype' header keyword but can be translated via an instrument file. If you want to force the zerocombine to process all images, try

cl> zerocombine *.fits ccdtype=""

Ya know that did it. I knew it had to be something brain dead! Got to stop using IRAF only once every 6 months so I don't forget these things!

Thanks!
