NAME

       fors_resample - Resample input spectra at constant wavelength step

SYNOPSIS

       esorex fors_resample [OPTIONS] FILE.sof

DESCRIPTION

       This recipe is used to resample at constant wavelength step spatially rectified spectra. The input frames
       are  produced  using either the recipe fors_extract_slits in the case of MOS/MXU multi slit exposures, or
       the recipes fors_remove_bias and fors_flatfield in the case of LSS or long-slit like MOS/MXU  data.  Only
       in  case  of  LSS or LSS-like data the SLIT_LOCATION table is required in input. Please refer to the FORS
       Pipeline User´s Manual for more details.

       In the table below the MXU acronym can also be read as MOS and LSS, SCI can be read as STD,  and  SCIENCE
       as STANDARD.

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_resample.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_resample.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_resample.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_resample.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.
