VIMOS_IMA_FRINGE(7)

💖 vimos_ima_fringe(7) — fringe frame creation for imaging 💖

okay bestie, welcome to vimos_ima_fringe, one of the little recipe stars of the vimos pipeline ✨ (the man page section is 7, iykyk). sit down, grab a strawberry 🍓, and let's get you fringed. no cap.

✨ SYNOPSIS ✨

esorex vimos_ima_fringe [OPTIONS] FILE.sof

that's it. that's the whole summoning ritual. you give it a SOF file and some options and it goes off 💅

---

🌸 DESCRIPTION 🌸

so vimos_ima_fringe is literally the VIMOS fringe frame creation recipe. that's its whole personality.

here's the vibe: you hand it a list of science frames, and it corrects them to strip out the bias, dark and flat field signatures. then it combines those images together to make a brand new master fringe frame. iconic behaviour honestly 👑

now, the SOF file — the program accepts these files in it:

• OBJECT — a list of raw science images
• MASTER_BIAS — a master bias frame
• MASTER_DARK — a master dark frame
• MASTER_TWILIGHT_FLAT — a master flat frame
• MASTER_CONF — a master confidence map
• MASTER_READGAIN — a master readgain table

and bestie, listen — all of these are required. every single one. no skipping, no "i'll do it later" 🫶

🎀 OPTIONS 🎀

• --prettynames <bool> — use pretty product names? it's a bool, default is False. the full name of this option for the EsoRex configuration file is vimos.vimos_ima_fringe.prettynames [default = False].
• --psm_ipix <int> — minimum pixel area for each detected object. int, default 5. the full name of this option for the EsoRex configuration file is vimos.vimos_ima_fringe.psm_ipix [default = 5].
• --psm_thresh <float> — detection threshold in sigma above sky. float, default 3.0. the full name of this option for the EsoRex configuration file is vimos.vimos_ima_fringe.psm_thresh [default = 3.0].
• --psm_nbsize <int> — background smoothing box size. int, default 64. the full name of this option for the EsoRex configuration file is vimos.vimos_ima_fringe.psm_nbsize [default = 64].

💡 heads up: you can totally create a configuration file containing these options, with suitable default values and everything. just please refer to the details provided by the esorex --help command. it's giving self-care for your configs 🧚
