<insert output of 'editpar extract-2dspec'>Then we run the commands to generate the ift0009_2spec.fits and ift0010_2spec.fits, respectively.
extract-2dspec -m ift0012 -f ift0009_s extract-2dspec -m ift0012 -f ift0010_s
Finally, we can use sumspec to stack the spectra and do some cosmic ray cleaning. The following command will generate CSIfld5_2spec.fits:
sumspec -o CSIfld5_2spec ift0009 ift0010
