💅 NACO_IMG_STREHL — the Strehl computation recipe bestie

okay so real talk, this is the man page for naco_img_strehl, part of the naco recipes fam (you'll see it written as NACO_IMG_STREHL(7) if you're being fancy about it). it estimates a Strehl ratio. she's giving very niche, very demure, very astronomy. let's get into it 🦋

✨ NAME ✨

naco_img_strehl — the Strehl computation recipe. that's it, that's the whole name, no notes 💖

🌸 SYNOPSIS 🌸

esorex naco_img_strehl [OPTIONS] FILE.sof

that's the summoning ritual. esorex, the recipe name, whatever [OPTIONS] you're feeling, and a .sof file. periodt.

👑 DESCRIPTION 👑

so naco_img_strehl is the NACO Strehl Ratio recipe, no cap.

what does it do? it estimates the strehl ratio and its error bound. that's the whole job. she's focused. she's a specialist. main character energy fr fr 🔥

now, the Set Of Frames (aka the sof-file, iykyk) has some requirements and you cannot skip them:

  • it must specify at least one pair of files — one pair minimum, bestie, don't come in here with a single file and expect results 💀
  • those files must be tagged either NACO-raw-file.fits CAL_PSF or NACO-raw-file.fits TECH_PSF

that's the vibe check. if your tags aren't right, the recipe is not going to be obsessed with you, and honestly? valid of her.

🎀 OPTIONS 🎀

here's the part where we go through literally every single option because I would never do you dirty like that. all three of these have full EsoRex configuration file names too, so you can put them in a config file and live your truth ✨

  • --star_r <float> — the star radius, measured in [arcsecond]. it's a float and the default is 2.0. the full name of this option for the EsoRex configuration file is naco.naco_img_strehl.star_r [default = 2.0].
  • --bg_r1 <float> — the internal radius of the background, in [arcsecond]. float, default 2.0. the full name of this option for the EsoRex configuration file is naco.naco_img_strehl.bg_r1 [default = 2.0].
  • --bg_r2 <float> — the external radius of the background, in [arcsecond]. float, default 3.0. the full name of this option for the EsoRex configuration file is naco.naco_img_strehl.bg_r2 [default = 3.0].
🫶 heads up bestie: you can create a configuration file containing these options, along with suitable default values. if you want the details on how to do that, please refer to the details provided by the 'esorex --help' command. she tells all.
