HAWKI_CAL_DISTORTION(7)

💖 hawki_cal_distortion(7) 💖

okay bestie, welcome to the hawki recipes corner of the manual, this is hawki_cal_distortion(7) and we're gonna get you comfy with it 🫶

✨ NAME ✨

hawki_cal_distortion — (OBSOLETE) Distortion autocalibration

ngl the (OBSOLETE) is right there in the name, bestie. it's giving "still documented, still real, but like… retired energy" 💀 keep that in mind, k?

🌈 SYNOPSIS 🌈

esorex hawki_cal_distortion [OPTIONS] FILE.sof

---

🎀 DESCRIPTION 🎀

(OBSOLETE) hawki_cal_distortion — HAWK-I distortion and astrometry autocalibration.

so here's the tea: the input files must be tagged like this:

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)

and the recipe creates these outputs for you ✨

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, iykyk: 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].

heads up fr fr: 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. 🧚
