.SH OPTIONS
.TP
\fB\-\-stack\-method\fR \fI<str>\fR
Stacking method: average, median, minmax or ksigma (str; default:
\'average\'). The full name of this option for the EsoRex configuration
file is \fBgiraffe.stacking.method\fR [default = \fIaverage\fR].
.TP
\fB\-\-stack\-ksigmalow\fR \fI<float>\fR
Lower threshold multiplier for method ksigma (float; default: 5.0). The full name of this option for the EsoRex configuration
file is \fBgiraffe.stacking.ksigma.low\fR [default = \fI5.0\fR].
.TP
\fB\-\-stack\-ksigmahigh\fR \fI<float>\fR
Upper threshold multiplier for method ksigma (float; default: 5.0). The full name of this option for the EsoRex configuration
file is \fBgiraffe.stacking.ksigma.high\fR [default = \fI5.0\fR].
.TP
\fB\-\-stack\-minreject\fR \fI<int>\fR
Minimum rejection level for method minmax (int; default: 1). The full name of this option for the EsoRex configuration
file is \fBgiraffe.stacking.minmax.minimum\fR [default = \fI1\fR].
.TP
\fB\-\-stack\-maxreject\fR \fI<int>\fR
Maximum rejection level for method minmax (int; default: 1). The full name of this option for the EsoRex configuration
file is \fBgiraffe.stacking.minmax.maximum\fR [default = \fI1\fR].
.TP
\fB\-\-mbias\-oscremove\fR \fI<bool>\fR
Remove pre\- and over\-scan regions from the created master bias image.
(bool; default: False). The full name of this option for the EsoRex configuration
file is \fBgiraffe.masterbias.overscan.remove\fR [default = \fIFalse\fR].
.TP
\fB\-\-mbias\-bpxclean\fR \fI<bool>\fR
Correct master bias image for bad pixels (bool; default: False). The full name of this option for the EsoRex configuration
file is \fBgiraffe.masterbias.badpixel.clean\fR [default = \fIFalse\fR].
.TP
\fB\-\-bpm\-create\fR \fI<bool>\fR
Create bad pixel map using a simple thresholding algorithm.
(temporary!) (bool; default: True). The full name of this option for the EsoRex configuration
file is \fBgiraffe.masterbias.bpm.create\fR [default = \fITrue\fR].
.TP
\fB\-\-bpm\-factor\fR \fI<float>\fR
Readout noise multiplier defining the valid range of pixel values for
searching bad pixels. (float; default: 5.0). The full name of this option for the EsoRex configuration
file is \fBgiraffe.masterbias.bpm.factor\fR [default = \fI5.0\fR].
.TP
\fB\-\-bpm\-frac\fR \fI<float>\fR
Maximum fraction of pixels which may be flagged as \'bad. If more
pixels are found to be \'bad a warning is issued. (float; default:
0.15). The full name of this option for the EsoRex configuration
file is \fBgiraffe.masterbias.bpm.fraction\fR [default = \fI0.15\fR].

.PP
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.
