OPTIONS

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

       --sex_config <str>
              SExtractor         configuration         file        (str;        default:        ´/usr/share/cpl-
              plugins/fors-5.5.7/config/fors.sex´). The full name of this option for  the  EsoRex  configuration
              file              is             fors.fors_zeropoint.sex_config             [default             =
              /usr/share/cpl-plugins/fors-5.5.7/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_zeropoint.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_zeropoint.sex_magerr [default = MAGERR_APER].

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

       --maxoffset <float>
              Maximum  acceptable  offset  between the image and catalogue WCS (pixels) (float; default: 150.0).
              The full name of this option for the EsoRex configuration  file  is  fors.fors_zeropoint.maxoffset
              [default = 150.0].

       --magcutE <float>
              Zeropoint  absolute cutoff (magnitude) (float; default: 1.0). The full name of this option for the
              EsoRex configuration file is fors.fors_zeropoint.magcutE [default = 1.0].

       --magcutk <float>
              Zeropoint kappa rejection parameter (float; default: 5.0). The full name of this  option  for  the
              EsoRex configuration file is fors.fors_zeropoint.magcutk [default = 5.0].

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

       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.
