NAME

       hawki_cal_distortion - Distortion autocalibration

SYNOPSIS

       esorex hawki_cal_distortion [OPTIONS] FILE.sof

DESCRIPTION

       hawki_cal_distortion -- HAWK-I distortion and astrometry autocalibration.

       The  input  files  must  be  tagged:  distortion_field.fits DISTOR_OBS sky_distortion.fits
       DISTOR_SKY   flat-file.fits   FLAT_IM   (optional)   dark-file.fits   DARK_IM   (optional)
       bpm-file.fits BPM (optional)

       The   recipe   creates   as   an  output:  hawki_cal_distortion_distx.fits  (DISTORTION_X)
       hawki_cal_distortion_disty.fits (DISTORTION_Y)

       The  recipe  performs  the  following  steps:  -Basic  calibration  of  astrometry  fields
       -Autocalibration of distortion, using method in A&A 454,1029 (2006)

       Return  code: esorex exits with an error code of 0 if the recipe completes successfully or
       1 otherwise

OPTIONS

       --sigma_det <float>
              detection level (float; default: 6.0). The full name of this option for the  EsoRex
              configuration file is hawki.hawki_cal_distortion.sigma_det [default = 6.0].

       --grid_points <long>
              number  of  points  in  distortion  grid  (long; default: 9). The full name of this
              option for the EsoRex configuration file is  hawki.hawki_cal_distortion.grid_points
              [default = 9].

       --borders <long>
              number  of  pixels to trim at the borders (long; default: 6). The full name of this
              option for the  EsoRex  configuration  file  is  hawki.hawki_cal_distortion.borders
              [default = 6].

       --subtract_linear <bool>
              Subtract a linear term to the solution (bool; default: True). The full name of this
              option       for       the        EsoRex        configuration        file        is
              hawki.hawki_cal_distortion.subtract_linear [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.
