VISIR_OLD_UTIL_DESTRIPE(7)

✨ visir_old_util_destripe ✨

okay bestie, listen up 💖 this is a page from the visir recipes manual, section 7, and it's all about a lil tool called visir_old_util_destripe. it's an Old DRS detector recipe whose whole entire job is: attempt to remove stripes in spectral data. yes. stripes. the annoying line-y ones. we hate them, we remove them, periodt 💅

🌸 NAME 🌸

visir_old_util_destripe — Old DRS detector: Attempt to remove stripes in spectral data

like literally, that's it. that's the mission. declutter the vibes, de-stripe the spectrum 🦋

---

🎀 SYNOPSIS 🎀

esorex visir_old_util_destripe [OPTIONS] FILE.sof

so you run esorex, you hand it the recipe name, you can sprinkle in [OPTIONS], and you give it a FILE.sof. simple as that, no cap ✨

---

💜 DESCRIPTION 💜

the files you list in the Set Of Frames (that's the sof-file, iykyk) must be tagged like this:

VISIR-chopnod-corrected-file.fits BKG_CORRECTED

and then the product(s) it spits out? they'll carry a FITS card that says HIERARCH ESO PRO CATG and its value will be:

DESTRIPED

slay. that's the whole description. your file goes in tagged, your file comes out de-striped and labeled. main character energy fr fr 👑

---

🔥 OPTIONS 🔥

two options, both iconic, both matter:

• --destripe_iterations <int> — Max number of destriping iterations (0 to disable destriping). Horizontal destriping is done first and if no horizontal striping is detected, vertical destriping is performed (int; default: 15). The full name of this option for the EsoRex configuration file is visir.visir_old_util_destripe.nstripe [default = 15].
• --destripe_morpho <bool> — Destripe with morphological cleaning (bool; default: False). The full name of this option for the EsoRex configuration file is visir.visir_old_util_destripe.mstripe [default = False].

heads up bestie — you can totally make a configuration file holding these options with your own cute default values 💖 just go peek at the details the esorex --help command gives you.

and like, quick recap of the order of operations because it's important: horizontal first, and only if no horizontal striping gets detected does it go vertical. also 0 disables destriping entirely — not me offering you an off switch 🫶

basic documentation about the EsoRex program can be found at the esorex(1) man page.

and fun fact — it is possible to call the pipelines from python using the python-cpl package. see https://packages.python.org/python-cpl/index.html for further information. python girlies, this one's for you 🐍💜
