Distortion autocalibration
esorex hawki_cal_distortion [OPTIONS] FILE.sof
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
--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.
