OPTIONS

--sex_exe <str>
SExtractor executable (str; default: ´/usr/bin/sex´). The full name of this option for the EsoRex configuration file is fors.fors_zeropoint.sex_exe [default = /usr/bin/sex].
--sex_config <str>
SExtractor configuration file (str; default: ´/usr/share/cpl- plugins/fors-5.4.3/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-5.4.3/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.
