Hi Perry,
sorry, should have known that this was not a good idea... Really any combine call
with plfile= arguments shows the "problem", like this
import pyraf
import pyraf.iraf as iraf
iraf.combine("FOV1,FOV2,FOV3","FOV123",plfile="FOV123_bpm")
(you can try with the files from http://www.aip.de/People/PWeilbacher/FOV.tar.gz).
But I found out now that it is the mscred package that is interfering.
If I remove it from my login.cl but leave imred and ccdred in, the above
command works from Python.
The question that remains is: could I explicitely call the combine task
from noao.imred.ccdred from Python, even if mscred is loaded? All of
these commands
iraf.ccdred.combine("LowResCube1_FOV,LowResCube2_FOV.fits,LowResCube3_FOV","FOV123",plfile="FOV_bpm")
iraf.noao.imred.ccdred.combine("LowResCube1_FOV,LowResCube2_FOV.fits,LowResCube3_FOV","FOV123",plfile="FOV_bpm")
from pyraf.iraf import ccdred
ccdred.combine("LowResCube1_FOV,LowResCube2_FOV.fits,LowResCube3_FOV","FOV123",plfile="FOV_bpm")
just give
IrafError: Cannot find .par file for task combine
even though Python itself seems to recognize them as valid calls.
Cheers,
Peter.

Thanks for providing the data and giving more specific information. I'm
not sure the problem is with the imports or something else. When I try
the following from ipython
import pyraf
from pyraf import iraf
from iraf import mscred
from iraf import imred
from iraf imoprt ccdred
iraf.noao.imred.ccdred.combine("FOV1, FOV2, FOV3", "FOV123",
plfile="FOV123_bpm")
works without any error messages as does:
iraf.combine("FOV1, FOV2, FOV3", "FOV123", plfile="FOV123_bpm")
though
iraf.mscred.combine("FOV1, FOV2, FOV3", "FOV123", plfile="FOV123_bpm")
fails as you describe.
If you do what I did, do you still have problems?
Thanks, Perry

Hi Perry,
below your commands I paste the output (in short) that I get.

Yes, see above. I also attach the full output in case you can tell any
more from that. Let me know if you have an idea, how to find the
difference between our setups.
