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.
