NAME

       hawki_cal_distortion - (OBSOLETE) Distortion autocalibration

SYNOPSIS

       esorex hawki_cal_distortion [OPTIONS] FILE.sof

DESCRIPTION

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

       --borders <int>
              number of pixels to trim at the borders (int; 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.
