πŸ’… visir_util_spc_txt2fits β€” bestie's guide to the VISIR recipes manual πŸ’…

okay so. sit down, hydrate, because we're talking about visir_util_spc_txt2fits from the visir recipes manual, and honestly? it's giving glow-up for your calibration tables. ✨


🌸 NAME 🌸

visir_util_spc_txt2fits β€” Generate spectrum calibration FITS tables πŸ’–

like, the whole point. txt goes in, FITS comes out. iconic behavior.


πŸŽ€ SYNOPSIS πŸŽ€

esorex visir_util_spc_txt2fits [OPTIONS] FILE.sof

that's it. that's the whole invocation. you hand it a .sof file and some [OPTIONS] and it works. periodt. πŸ’…


✨ DESCRIPTION ✨

so this recipe is your girl for generating spectrum calibration tables. that's her job, that's her purpose, she's booked and busy. 🫢

your sof file? it shall consist of 1 line, and that line has the name of an ASCII-file. that file is currently tagged with either SPC_LINES_ASCII or SPC_QEFF_ASCII. one tag, one file, no chaos. πŸ¦‹

and the file itself must comprise two columns:

  1. 1st column: must be wavelengths in increasing order in units of meter 🌈
  2. 2nd column: for SPC_LINES_ASCII-files this must be the atmospheric emission, while for SPC_QEFF_ASCII-files it must be the quantum efficiency of the detector.
ngl bestie, "increasing order in units of meter" is not a suggestion, it's a vibe check you have to pass. πŸ’€

then the output does its little transformation moment:

  • a SPC_LINES_ASCII-file will generate a SPEC_CAL_LINES-file πŸŽ€
  • a SPC_QEFF_ASCII-file will generate a SPEC_CAL_QEFF-file ✨

and for the lore: the current SPEC_CAL_LINES- and SPEC_CAL_QEFF-files are generated using the ASCII-files in the catalogs/ directory of the VISIR source-code distribution. iykyk. πŸ“


πŸ‘‘ OPTIONS πŸ‘‘

--qeff <float>

  • --qeff <float> β€” Ignored. like, genuinely ignored. it's a float and the default is 1.0. πŸ™ˆ

the full name of this option for the EsoRex configuration file is:

visir.visir_util_spc_txt2fits.qeff [default = 1.0]

so if you were like "ooh a knob to turn" β€” no bestie, this knob is decorative. it's a display-only candle. πŸ•―οΈ


πŸ’– friendly reminder: 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. that's where the real tea is. β˜•
