NAME

       visir_img_ff - Flat field recipe

SYNOPSIS

       esorex visir_img_ff [OPTIONS] FILE.sof

DESCRIPTION

       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

OPTIONS

       --low <float>
              Low threshold for the bad pixel map (float; default: 0.2). The full name of this  option  for  the
              EsoRex configuration file is visir.visir_img_ff.low [default = 0.2].

       --high <float>
              High  threshold  for the bad pixel map (float; default: 5.0). The full name of this option for the
              EsoRex configuration file is visir.visir_img_ff.high [default = 5.0].

       Note that it is possible to create a configuration file containing these  options,  along  with  suitable
       default values. Please refer to the details provided by the 'esorex --help' command.
