💅 vimos_ima_bias — bias combination for imaging 💅

okay so bestie, welcome to VIMOS_IMA_BIAS(7), one of the vimos recipes, and honestly? she's giving quiet-but-essential. let's get into it 🫶

✨ NAME ✨

vimos_ima_bias — bias combination for imaging. that's the whole vibe. combining biases. iconic behaviour, no notes. 👑

🌸 SYNOPSIS 🌸

esorex vimos_ima_bias [OPTIONS] FILE.sof

that's it. that's the summoning ritual. ✨

🦋 DESCRIPTION 🦋

so vimos_ima_bias is the VIMOS bias combine recipe, periodt.

what she does: takes a whole list of bias frames and combines them into a mean bias frame. and optionally — like, if you're feeling fancy — she'll compare that output frame to a reference bias frame. lowkey a vibe check for your bias. 😌

🎀 the files she accepts in the SOF

  • BIAS — a list of raw bias images. the main characters fr fr.
  • REFERENCE_BIAS — optional reference bias frame. 💖
real talk though: if no reference bias frame is made available, then no comparison will be done. which means there will be no output difference image and no stats table. so like, nothing to screenshot for the group chat. 💀

💖 OPTIONS 💖

every single one, in order, no skipping, because we don't do that here:

  • --combtype <str> — the combination algorithm (str; default: median). the full name of this option for the EsoRex configuration file is vimos.vimos_ima_bias.combtype [default = median].
  • --xrej <bool> — True if using extra rejection cycle (bool; default: True). the full name of this option for the EsoRex configuration file is vimos.vimos_ima_bias.xrej [default = True].
  • --thresh <float> — rejection threshold in sigma above background (float; default: 5.0). the full name of this option for the EsoRex configuration file is vimos.vimos_ima_bias.thresh [default = 5.0].
  • --ncells <int> — number of cells for diff image stats (int; default: 64). the full name of this option for the EsoRex configuration file is vimos.vimos_ima_bias.ncells [default = 64].
  • --prettynames <bool> — use pretty output file names? (bool; default: False). the full name of this option for the EsoRex configuration file is vimos.vimos_ima_bias.prettynames [default = False].
also bestie — 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. go check her out, she knows things. 🧚
