NAME

fors_wave_calib - Derive dispersion relation from rectified arc lamp frame

SYNOPSIS

esorex fors_wave_calib [OPTIONS] FILE.sof

DESCRIPTION

This recipe is used to wavelength calibrate MOS/MXU slit spectra contained in the recti‐ fied arc lamp exposure produced with recipe fors_extract_slits. A pattern-matching algorithm is applied as in recipe fors_detect_spectra. The input spatial map is used in the production of the wavelength map. Use recipe fors_wave_calib_lss for LSS data, or for MOS/MXU data where all slits have the same offset. For more details on this data reduction strategy please refer to the FORS Pipeline User´s Manual. Note that specifying an input GRISM_TABLE will set some of the recipe configuration param‐ eters to default values valid for a particular grism. In the table below the MXU acronym can be alternatively read as MOS.

OPTIONS

--dispersion <float> Expected spectral dispersion (Angstrom/pixel) (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_wave_calib.dispersion [default = 0.0]. --peakdetection <float> Initial peak detection threshold (ADU) (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_wave_calib.peakdetection [default = 0.0]. --wdegree <long> Degree of wavelength calibration polynomial (long; default: 0). The full name of this option for the EsoRex configuration file is fors.fors_wave_calib.wdegree [default = 0]. --wradius <long> Search radius if iterating pattern-matching with first-guess method (long; default: 4). The full name of this option for the EsoRex configuration file is fors.fors_wave_calib.wradius [default = 4]. --wreject <float> Rejection threshold in dispersion relation fit (pixel) (float; default: 0.7). The full name of this option for the EsoRex configuration file is fors.fors_wave_calib.wreject [default = 0.7]. --wcolumn <str> Name of line catalog table column with wavelengths (str; default: ´WLEN´). The full name of this option for the EsoRex configuration file is fors.fors_wave_calib.wcol‐ umn [default = WLEN]. --startwavelength <float> Start wavelength in spectral extraction (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_wave_calib.startwave‐ length [default = 0.0]. --endwavelength <float> End wavelength in spectral extraction (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_wave_calib.endwavelength [default = 0.0]. 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.
