# muse\_scipost\_subtract\_sky\_simple(7)

Subtract night sky spectrum.

## NAME

muse\_scipost\_subtract\_sky\_simple - Subtract night sky spectrum.

## SYNOPSIS

esorex **muse\_scipost\_subtract\_sky\_simple** \[OPTIONS\] FILE.sof

## DESCRIPTION

Subtract the sky in a simple way, just using a sky spectrum created by muse\_create\_sky. This is a separated task of muse\_scipost.

## OPTIONS

- **--lambdamin** *\<float\>*

  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 **muse.muse\_scipost\_subtract\_sky\_simple.lambdamin** \[default = *4000.0*\].

- **--lambdamax** *\<float\>*

  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 **muse.muse\_scipost\_subtract\_sky\_simple.lambdamax** \[default = *10000.0*\].

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.
