💖 MAKENOISE(1) — the group chat version 💖

okay so bestie, this is a User Commands page for MakeNoise, and I'm about to make it make sense. pull up a chair, grab a strawberry 🍓, and let's go.

✨ NAME ✨

MakeNoise — add noise to an image 🦋

no cap, that's the whole job. it adds noise. to an image. iconic behavior honestly.

🌸 SYNOPSIS 🌸

astmknoise [OPTION...] ASTRdata

yes bestie, the program is invoked as astmknoise even though the page is called MakeNoise. that's just how Gnuastro does it. iykyk 💅

💜 DESCRIPTION 💜

MakeNoise is part of GNU Astronomy Utilities 0.19. it will add noise to all the pixels in an input dataset. the noise parameters can be specified with the options below. periodt.

for more information, please run any of the following commands. in particular the second contains a very comprehensive explanation of MakeNoise's invocation: expected input(s), output(s), and a full description of all the options. like, the whole vibe check 👑

all options and their values:

$ astmknoise -P

inputs/outputs and options:

$ info astmknoise

full section in manual/book:

$ info MakeNoise

full Gnuastro manual/book:

$ info gnuastro

if you couldn't find your answer in the manual, you can get direct help from experienced Gnuastro users and developers. for more information, please run:

$ info help-gnuastro
not me telling you to read the docs before you @ me. the manual literally ate, bestie, go look 🫶

🎀 OPTIONS 🎀

MakeNoise options, grouped all cute like:

⭐ Input:

  • -b, --background=FLT — fixed background magnitude for the whole input.
  • -h, --hdu=STR/INT — extension name or number of the input data.
  • -i, --instrumental=FLT — instrument noise level (in pixel value units).
  • -I, --ignorecase — ignore case when matching/searching columns.
  • -s, --sigma=FLT — total noise sigma; this one ignores the other options. main character energy, it doesn't share the spotlight 😭
  • -z, --zeropoint=FLT — zeropoint magnitude of the input.

🌈 Output:

  • -D, --dontdelete — don't delete the output if it already exists.
  • -K, --keepinputdir — keep the input directory for automatic output.
  • -o, --output=STR — output file name.
  • -T, --type=STR — type of the output, e.g., int16, float32, etc...
  • --wcslinearmatrix=STR — WCS linear matrix of the output, either 'pc' or 'cd'.

🧚 Operating modes:

  • -?, --help — give this help list.
  • -B, --bgisbrightness — background is brightness, not magnitude.
  • --checkconfig — list all config files and variables read.
  • --cite — BibTeX citation for this program.
  • --config=STR — read configuration file STR immediately.
  • -e, --envseed — use the GSL_RNG_SEED environment variable for the seed.
  • --lastconfig — do not parse any more configuration files.
  • --log — information about the output(s) goes in a log file.
  • --minmapsize=INT — minimum number of bytes to avoid RAM automatically.
  • -N, --numthreads=INT — number of CPU threads to use.
  • --onlyversion=STR — only run if the program version is STR.
  • -P, --printparams — print the parameter values to be used and abort.
  • --quietmmap — don't print the mmap'd file's name and size.
  • -q, --quiet — only report errors, and remain quiet about the steps.
  • -S, --setdirconf — set default values for this directory and abort.
  • --usage — give a short usage message.
  • -U, --setusrconf — set default values for this user and abort.
  • -V, --version — print the program version.

mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options. (yes, the short and long versions are a package deal, they're a duo, a duo 💖)
