.SH NAME
muse_scipost_subtract_sky \- Subtract night sky model.

.SH SYNOPSIS
esorex
.B muse_scipost_subtract_sky
[OPTIONS] FILE.sof

.SH DESCRIPTION
Subtract the sky as defined by the sky lines and continuum from a pixel table. This is a separated task of muse_scipost.

.SH OPTIONS
.TP
\fB\-\-lambdamin\fR \fI<float>\fR
Cut off the data below this wavelength after loading the pixel
table(s). (float; default: 4000.0). The full name of this option for the EsoRex configuration
file is \fBmuse.muse_scipost_subtract_sky.lambdamin\fR [default = \fI4000.0\fR].
.TP
\fB\-\-lambdamax\fR \fI<float>\fR
Cut off the data above this wavelength after loading the pixel
table(s). (float; default: 10000.0). The full name of this option for the EsoRex configuration
file is \fBmuse.muse_scipost_subtract_sky.lambdamax\fR [default = \fI10000.0\fR].
.TP
\fB\-\-orig\fR \fI<str>\fR
If specified, write an additional column containing the original data
to the pixel table. (str; default: \'\'). The full name of this option for the EsoRex configuration
file is \fBmuse.muse_scipost_subtract_sky.orig\fR [default = \fI\fR].
.TP
\fB\-\-flux_sky\fR \fI<float>\fR
Reference flat field flux, obtained by sky exposure. This parameter is
needed to scale the data of each pixel table if more than one pixel
table was used to determine the sky. By default, it is taken from the
parameter ESO DRS MUSE FLAT FLUX SKY of the first pixel table. (float;
default: 0.0). The full name of this option for the EsoRex configuration
file is \fBmuse.muse_scipost_subtract_sky.flux_sky\fR [default = \fI0.0\fR].
.TP
\fB\-\-flux_lamp\fR \fI<float>\fR
Reference flat field flux, obtained by lamp exposure. This parameter
is needed to scale the data of each pixel table if more than one pixel
table was used to determine the sky. By default, it is taken from the
parameter ESO DRS MUSE FLAT FLUX LAMP of the first pixel table.
(float; default: 0.0). The full name of this option for the EsoRex configuration
file is \fBmuse.muse_scipost_subtract_sky.flux_lamp\fR [default = \fI0.0\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.
