I'm a Pyraf user, and I think that it may have something to do with my problem, but I am using imarith to multiply a constant by a non MEF fits file, and for whatever reason, it is outputting a MEF when I don't want to it. Here is my surrounding code:
PHP Formatted Code
iraf .datapars .readnoise =pyfits .getval (filesfull [i ]+'.fits','RONOISE')
iraf .imarith (operand1 = filesfull [i ], op ='*', operand2 = trval , result = files [i ]+'z.fits')
iraf .photpars .zmag = -2.5*math .log10(1.213*3.384638*math .pow(10,-5)/(280.9*trval ))
iraf .daofind (image = files [i ] + 'z.fits', output = files [i ]+'z.coo')
iraf .phot (image =files [i ] + 'z.fits', coords =files [i ]+'z.coo', output = files [i ]+'z.mag')
iraf .txdump (textfile = files [i ]+'z.mag', fields = 'xc,yc,mag,merr,xerr,yerr', expr = 'merr<0.1', Stdout = files [i ]+'z.txt')
Where trval is just a constant, and the code breaks on daofind, with the following error:
ERROR (1113, "FXF: must specify which FITS extension (r47124224/ch1/bcd/SPITZER_I1_47124224_0001_0000_1_cbcdz.fits)")
If there's any advice you can give, that would be wonderful!

I'm unable to reproduce this using the standard CL so it may be a pyraf issue. If you're still having problems then I'd suggest contacting the STScI help desk (help@stsci.edu) to see if it is a known problem. Does creating the filename strings outside of the task call change anything, e.g.
resname = files + 'z.fits'
iraf.imarith ( ......., result=resname)
Have you tried running the same imarith command under the CL with the same result?
