SYNOPSISesorex fors_extract_slits [OPTIONS] FILE.sof
DESCRIPTIONThis 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.

- --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.
