fors_config - Creation of FORS recipes configuration tables

esorex fors_config [OPTIONS] FILE.sof

This recipe is used to create the so-called GRISM_TABLE, containing all the FORS spectral pipeline configuration parameters related to a specific grism. This is a way to provide for each specific instrument mode a set of appropriate defaults for the recipe parameters.

The values assigned to each input parameter of fors_config are simply copied to a FITS table consisting of one row, and as many columns as the input parameter: each column will have the same name and type of each parameter. Only the three parameters "instrument", "grism", and "id" are not written to the table columns, but to the descriptor header keywords INSTRUME, ESO INS GRIS1 NAME, and ESO INS GRIS1 ID, that will be used by the automatic pipeline for appropriate data association.

Expected spectral dispersion (Angstrom/pixel) (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_config.dispersion [default = 0.0].
Peak detection threshold (ADU) (float; default: 250.0). The full name of this option for the EsoRex configuration file is fors.fors_config.peakdetection [default = 250.0].
Degree of wavelength calibration polynomial (int; default: 4). The full name of this option for the EsoRex configuration file is fors.fors_config.wdegree [default = 4].
Degree of spectral curvature polynomial (int; default: 4). The full name of this option for the EsoRex configuration file is fors.fors_config.cdegree [default = 4].
Start wavelength in spectral extraction (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_config.startwavelength [default = 0.0].
End wavelength in spectral extraction (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_config.endwavelength [default = 0.0].
Name of instrument (str; default: ´0´). The full name of this option for the EsoRex configuration file is fors.fors_config.instrument [default = 0].
Name of grism (str; default: ´0´). The full name of this option for the EsoRex configuration file is fors.fors_config.grism [default = 0].
Grism ID (str; default: ´0´). The full name of this option for the EsoRex configuration file is fors.fors_config.grism_id [default = 0].
Name of filter (str; default: ´0´). The full name of this option for the EsoRex configuration file is fors.fors_config.filter [default = 0].
Filter ID (str; default: ´0´). The full name of this option for the EsoRex configuration file is fors.fors_config.filter_id [default = 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.

Basic documentation about the EsoRex program can be found at the esorex (1) man page.

It is possible to call the pipelines from python using the python-cpl package. See https://packages.python.org/python-cpl/index.html for further information.
