SYNOPSISesorex fors_wave_calib [OPTIONS] FILE.sof
DESCRIPTIONThis recipe is used to wavelength calibrate MOS/MXU slit spectra contained in the rectified 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 parameters to default values valid for a particular grism.
In the table below the MXU acronym can be alternatively read as MOS.

- --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.wcolumn [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.startwavelength [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.
