muse_scipost_raman7

Usage

Overview

This recipe removes the Raman scattered light of the 4GLSF system from the exposure. It must be before the normal sky subtraction.

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_raman.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_raman.lambdamax [default = 10000.0].

--lambdaref <float>

Reference wavelength used for correction of differential atmospheric refraction. The R-band (peak wavelength ~7000 Angstrom) that is usually used for guiding, is close to the central wavelength of MUSE, so a value of 7000.0 Angstrom should be used if nothing else is known. A value less than zero switches DAR correction off. (float; default: 7000.0). The full name of this option for the EsoRex configuration file is muse.muse_scipost_raman.lambdaref [default = 7000.0].

--width <float>

Wavelength range around Raman lines [Angstrom]. (float; default: 20.0). The full name of this option for the EsoRex configuration file is muse.muse_scipost_raman.width [default = 20.0].

--crsigma <float>

Sigma level clipping for cube-based CR rejection (using "median", see muse_scipost). It can be switched off, by passing zero or a negative value. (float; default: 15.0). The full name of this option for the EsoRex configuration file is muse.muse_scipost_raman.crsigma [default = 15.0].

--fraction <float>

Fraction of the image (without the ignored part) to be considered as sky. If an input sky mask is provided, the fraction is applied to the regions within the mask. If the whole sky mask should be used, set this parameter to 1. (float; default: 0.75). The full name of this option for the EsoRex configuration file is muse.muse_scipost_raman.fraction [default = 0.75].

--ignore <float>

Lowest fraction of the image to be ignored. If an input sky mask is provided, the fraction is applied to the regions within the mask. If the whole sky mask should be used, set this parameter to 0. (float; default: 0.05). The full name of this option for the EsoRex configuration file is muse.muse_scipost_raman.ignore [default = 0.05].

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.
