.SH OPTIONS
.TP
\fB\-\-magsyserr\fR \fI<float>\fR
Systematic error in magnitude (float; default: 0.01). The full name of this option for the EsoRex configuration
file is \fBfors.fors_img_science.magsyserr\fR [default = \fI0.01\fR].
.TP
\fB\-\-sex_exe\fR \fI<str>\fR
SExtractor executable (str; default: \'/usr/bin/sex\'). The full name of this option for the EsoRex configuration
file is \fBfors.fors_img_science.sex_exe\fR [default = \fI/usr/bin/sex\fR].
.TP
\fB\-\-sex_config\fR \fI<str>\fR
SExtractor configuration file (str; default: \'/usr/share/cpl\-
plugins/fors\-5.3.32/config/fors.sex\'). The full name of this option for the EsoRex configuration
file is \fBfors.fors_img_science.sex_config\fR [default = \fI/usr/share/cpl\-plugins/fors\-5.3.32/config/fors.sex\fR].
.TP
\fB\-\-sex_mag\fR \fI<str>\fR
SExtractor magnitude (str; default: \'MAG_APER\'). The full name of this option for the EsoRex configuration
file is \fBfors.fors_img_science.sex_mag\fR [default = \fIMAG_APER\fR].
.TP
\fB\-\-sex_magerr\fR \fI<str>\fR
SExtractor magnitude error (str; default: \'MAGERR_APER\'). The full name of this option for the EsoRex configuration
file is \fBfors.fors_img_science.sex_magerr\fR [default = \fIMAGERR_APER\fR].
.TP
\fB\-\-sex_radius\fR \fI<int>\fR
Background error map median filter radius (unbinned pixels) (int;
default: 64). The full name of this option for the EsoRex configuration
file is \fBfors.fors_img_science.sex_radius\fR [default = \fI64\fR].

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.
