fors_extract_slits - Spatial rectification of spectral image

FORS_EXTRACT_SLITS(7) fors recipes FORS_EXTRACT_SLITS(7)

NAME

fors_extract_slits - Spatial rectification of spectral image
 

SYNOPSIS

esorex fors_extract_slits [OPTIONS] FILE.sof
 

DESCRIPTION

This recipe is used to extract MOS/MXU slit spectra, following their curvature, and to remap them into a spatially rectified image.
Please refer to the FORS Pipeline User´s Manual for details about the spectra remapping technique. Note however that the interpolation is done exclusively along the spatial direction, and therefore the output rectified image will have the same x size of the input spectral image.
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_extract_slits.dispersion [default = 0.0].
--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_extract_slits.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_extract_slits.endwavelength [default = 0.0].
--flux <bool>
Apply flux conservation (bool; default: True). The full name of this option for the EsoRex configuration file is fors.fors_extract_slits.flux [default = True].
 
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.
