HAWKI_STEP_COMPUTE_BKG(7)

💖 HAWKI_STEP_COMPUTE_BKG 💖

okay so bestie, welcome to the hawki recipes section of the manual — this one's called hawki_step_compute_bkg(7) and she's here to talk about backgrounds. yes, the vibes behind your objects. let's get into it 🫶

✨ NAME ✨

hawki_step_compute_bkg — (OBSOLETE) Background computing utility

ngl the "(OBSOLETE)" is right there in the name, bestie. she's serving retired icon energy. still documented, still real, just… retired. 💀

---

🌈 SYNOPSIS 🌈

esorex hawki_step_compute_bkg [OPTIONS] FILE.sof

---

🦋 DESCRIPTION 🦋

(OBSOLETE) hawki_step_compute_bkg — it's the hawki background computation utility, periodt.

So here's the tea: this recipe makes the associated background images for a given set of object images. 🎀

• if there are sky images, those get used to compute the background
• otherwise, the background is computed using a running mean on the object images
• and an optional mask can be supplied for that running mean 👑

The files listed in the Set Of Frames (sof-file) must be tagged like this:

• obj_basic_cal-file.fits → BASIC_CALIBRATED
• sky_basic_cal-file.fits → SKY_BASIC_CALIBRATED

and optionally, for object masking:

• object_mask-file.fits → OBJ_MASK
• offsets.fits → OFFSETS_REFINED
• distortion_x.fits → DISTORTION_X
• distortion_y.fits → DISTORTION_Y

like, the tags are not optional, the masking files are optional. read it again if u need to, i'll wait 💅

✨ OPTIONS ✨

• --nmin_comb <int> — minimum number of jitter frames needed to use the running median (int; default: 10). The full name of this option for the EsoRex configuration file is hawki.hawki_step_compute_bkg.nmin_comb [default = 10].
• --nhalf_window <int> — number of images at both sides of the current ima to use for bkg in running median (int; default: 7). The full name of this option for the EsoRex configuration file is hawki.hawki_step_compute_bkg.nhalf_window [default = 7].
• --rejlow <int> — the number of frames with low level to reject (int; default: 2). The full name of this option for the EsoRex configuration file is hawki.hawki_step_compute_bkg.rejlow [default = 2].
• --rejhigh <int> — the number of frames with high level to reject (int; default: 2). The full name of this option for the EsoRex configuration file is hawki.hawki_step_compute_bkg.rejhigh [default = 2].

and fyi bestie — 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. 🔥

okay that's the whole page bestie, you ate 💅✨ this was hawki_step_compute_bkg version 2.4.11, straight from the hawki recipes collection — go forth and compute those backgrounds, ily 🫶🎀
