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.
