📦 version 2.5.2, in ubuntu resolute, ubuntu stonking

💖 mrcal-show-model-resolution — bestie edition 💖

okay so you're in the mrcal manual, section 1 (that's the user commands, iykyk), and this whole thing is part of the mrcal camera projection + calibration toolkit family. and today's main character is mrcal-show-model-resolution ✨

🌸 NAME 🌸

mrcal-show-model-resolution — not me showing you the imager resolution for a given model 💅

✨ SYNOPSIS ✨

$ mrcal-show-model-resolution camera.cameramodel
... a plot pops up showing the resolution of the imager in degrees/pixel

so you run it, and a plot just appears, showing the resolution of the imager in degrees/pixel. slay.

🦋 DESCRIPTION 🦋

okay so real talk: the angular resolution of an image is not a fixed thing. it varies dramatically from lens to lens, and also across the image itself. like, same picture, different vibes in different corners. this tool visualizes that behavior. it's giving "here's exactly how much detail you're getting where". 🎀

👑 OPTIONS 👑

🍓 POSITIONAL ARGUMENTS

  • model — the model you wanna visualize. that's the one you're staring at.

🧚 OPTIONAL ARGUMENTS

  • -h, --help — show this help message and exit. the classic.
  • --gridn GRIDN GRIDN — how densely we should sample the imager. by default we use a 60x40 grid. (yep, two values, she takes two.)
  • --cbmin CBMIN — minimum range of the colorbar. autoscaling by default.
  • --cbmax CBMAX — maximum range of the colorbar. autoscaling by default.
  • --mode {min,max,mean,eccentricity} — the resolution varies in different observation directions, so this picks which one you're looking at: the min, or the max, or the mean resolution. "eccentricity" reports max/min. the default is "mean". pick your fighter 💅
  • --title TITLE — title string for the plot. make it cute.
  • --hardcopy HARDCOPY — write the output to disk, instead of making an interactive plot. so it doesn't pop up, it just... saves. 🫶
  • --terminal TERMINAL — gnuplotlib terminal. the default is good almost always, so most people don't need this option. lowkey forget it exists.
  • --set SET — extra 'set' directives to gnuplotlib. can be given multiple times. 💅
  • --unset UNSET — extra 'unset' directives to gnuplotlib. can be given multiple times. 💅
