wspectext ERROR: Cannot open pixel file

David Stops wrote on Oct 26, 2009

I'm trying to extract a 1d spectra from a fits file using

wspectext NAMEex.fits[*,2] NAME.txt

On NOAO PC-IRAF Revision 2.12.2-EXPORT on Debian Linux, I get the error below

ERROR: Cannot open pixel file (obj16ex.fits[*,2])

When I try the same thing on NOAO/IRAFNET PC-IRAF Revision 2.14
on Mac OS X I do not get any errors

I thought it might be the imdir variable but it seems to be set
sensibly

What is going wrong ?

Thank you

David

If you can e.g. IMSTAT the fits file then there isn't a general problem reading the file and the section "[*,2]" may not be valid. Is this a 2-D FITS file or a 2-D spectrum? Another possible problem is that the file is truncated on the Debian system (i.e. not an even multiple of 2880 bytes). The imdir variable is used when creating a new .imh image and isnt' used when reading a FITS file.

Thanks for the suggestion. I seem to have solved the problem
by updating my version of IRAF running on Debian
