💖 VISIR_IMG_TRANS 💖

okay bestie, welcome to visir_img_trans(7) — yes it's the Instrument Transmission recipe, and yes it's lowkey the main character of this corner of the visir pipeline. let's get into it 🫶

✨ NAME ✨

visir_img_trans — the Instrument Transmission recipe. that's it, that's the name, and it ate. 💅

🌈 SYNOPSIS 🌈

esorex visir_img_trans [OPTIONS] FILE.sof

like, you run it with esorex, you throw your options at it, you hand it a .sof file. periodt. ✨

🦋 DESCRIPTION 🦋

so here's the vibe: this recipe computes the transmission at different wavelengths by comparing the flux of a bright star for different observations. basically it's comparing glow-ups across observations to figure out how much light actually made it through. 💫

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

VISIR-transmission-file.fits IM_TEC_TRANS

the resuts are given in a table. (yes, "resuts" — we keep the typo fr fr, it's part of the lore now 💀)

🎀 OPTIONS 🎀

ngl bestie, there's no big dramatic flag list here, but there IS a very important note:

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 yeah — config file? possible. default values? sure. where do you find the deets? esorex --help. go read it, bestie, it's giving documentation. 🍓
