esorex fors_resample [OPTIONS] FILE.sof


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.

Input files:

  DO category:               Type:       Explanation:         Required:
  or RECTIFIED_SKY_SCI_MXU   Calib       Frame to resample       Y
  or DISP_COEFF_SCI_MXU      Calib       Dispersion coefficients Y
  SLIT_LOCATION_MXU          Calib       Slit location table     Y
  GRISM_TABLE                Calib       Grism table             .

--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.
