This recipe computes the flatfield.

The files listed in the Set Of Frames (sof-file) must be tagged either VISIR-flatfield-raw-file.fits IM_CAL_FLAT or VISIR-flatfield-raw-file.fits IM_TECH_FLAT or VISIR-flatfield-raw-file.fits SPEC_CAL_FLAT or VISIR-flatfield-raw-file.fits SPEC_TECH_FLAT

The corresponding primary product will have a FITS card ´HIERARCH ESO PRO CATG´ with a value of IMG_FF or IMG_FF_TECH or SPEC_FF or SPEC_FF_TECH
