🎀 naco_img_lampflat — the manual page, bestie edition 🎀

okay so this is naco_img_lampflat(7), straight out of the naco recipes section of the manual, and it's genuinely iconic for one very specific job. sit down, grab a snack, let's get into it. 💅

✨ NAME ✨

naco_img_lampflat — the flat recipe that uses a lamp. that's it, that's the whole vibe. 🔥

✨ SYNOPSIS ✨

esorex naco_img_lampflat [OPTIONS] FILE.sof

yes bestie, that's literally it. you run esorex, you feed it the recipe name, you hand it a .sof file, and you go. 🦋

✨ DESCRIPTION ✨

so naco_img_lampflat is the NACO imaging flat-field creation recipe, and it builds that flat field out of lamp images. no cap. 💖

the files you list inside your Set Of Frames (that's the sof-file, iykyk) have to be tagged exactly like this:

NACO-raw-file.fits CAL_FLAT_LAMP

and here's the part people forget and then get confused about — the input set of frames must have values of the FITS key ESO INS LAMP2 SET that alternate between zero and non-zero, with the non-zero one coming first, for the first frame. alternating. zero, non-zero, zero, non-zero. it's giving pattern. it's giving rhythm. 🌈

also, real talk: it's further required that the light from the lamp sits in a range without a significant thermal background. don't skip that, it matters. 🫶

✨ OPTIONS ✨

  • --r <str> — this is your rejected border, the left, right, bottom and top border in pixels, all in one little string. it's type str, and the default is 200 200 200 200. the full name of this option for the EsoRex configuration file is naco.naco_img_lampflat.rej_bord, and yes the default is 200 200 200 200 there too. 💅
heads up bestie: you can absolutely create a configuration file that holds these options along with suitable default values. the details for that live in the esorex --help command. go look, it's worth it. ✨

✨ SEE ALSO ✨

the full documentation for the naco pipeline can be downloaded as a PDF file using this URL right here:

ftp://ftp.eso.org/pub/dfs/pipelines/naco/naco-pipeline-manual-1.1.pdf

and an overview over the existing ESO pipelines? found on this web page:

https://www.eso.org/sci/software/pipelines/

basic documentation about the EsoRex program lives at the esorex(1) man page. 📖

and — not me hyping this up — 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, we ate. 🐍💜

the other recipes of the naco pipeline are, in order, because I will not be skipping a single one of my sisters:

a whole friend group, honestly. 🎀
