OPTIONS

       --magsyserr <float>
              Systematic  error in magnitude (float; default: 0.01). The full name of this option
              for the EsoRex configuration file  is  fors.fors_img_science.magsyserr  [default  =
              0.01].

       --sex_exe <str>
              SExtractor  executable (str; default: ´/usr/bin/sex´). The full name of this option
              for the EsoRex  configuration  file  is  fors.fors_img_science.sex_exe  [default  =
              /usr/bin/sex].

       --sex_config <str>
              SExtractor      configuration      file     (str;     default:     ´/usr/share/cpl-
              plugins/fors-4.11.12/config/fors.sex´). The full name of this option for the EsoRex
              configuration     file     is     fors.fors_img_science.sex_config    [default    =
              /usr/share/cpl-plugins/fors-4.11.12/config/fors.sex].

       --sex_mag <str>
              SExtractor magnitude (str; default: ´MAG_APER´). The full name of this  option  for
              the   EsoRex   configuration   file  is  fors.fors_img_science.sex_mag  [default  =
              MAG_APER].

       --sex_magerr <str>
              SExtractor magnitude error (str; default: ´MAGERR_APER´). The  full  name  of  this
              option  for  the  EsoRex  configuration  file  is  fors.fors_img_science.sex_magerr
              [default = MAGERR_APER].

       --sex_radius <long>
              Background error map median filter radius (unbinned pixels)  (long;  default:  64).
              The   full   name   of   this   option   for   the  EsoRex  configuration  file  is
              fors.fors_img_science.sex_radius [default = 64].

       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.
