✨ HAWKI_STEP_SUBTRACT_BKG ✨

okay bestie, welcome to the hawki_step_subtract_bkg(7) manual page — part of the hawki recipes, section 7, and yes she's serving OBSOLETE energy 💅

💖 NAME 💖

hawki_step_subtract_bkg — (OBSOLETE) Background subtraction utility 🫶

🌸 SYNOPSIS 🌸

esorex hawki_step_subtract_bkg [OPTIONS] FILE.sof

🦋 DESCRIPTION 🦋

so. (OBSOLETE) hawki_step_subtract_bkg — it's the hawki background subtraction utility, fr fr.

This recipe will subtract the given background to the science images. that's the whole job. that's her job.

You can get that background from the sky or object images using the hawki_util_compute_bkg utility ✨

There are two modes of operation, bestie, and you gotta pick your vibe:

  1. One single background image that it is subtracted to all object images. one bkg, every object. she's a sharer.
  2. As many background images as objects. A one to one relationship is applied. very main character energy, everyone gets their own.

The files listed in the Set Of Frames (sof-file) must be tagged like this, no cap:

  • obj_basic_cal-file.fits BASIC_CALIBRATED
  • background-file.fits BKG_IM

🎀 OPTIONS 🎀

lowkey there are no options listed here, but listen:

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.

so go ask esorex, she knows 💅
