GIMASTERBIAS(7)

💅 GIMASTERBIAS — the giraf recipes glow-up (section 7, bestie)

okay so. this is gimasterbias(7), one of the giraf recipes, and it is literally the one that builds you a master bias image out of a pile of raw biases. she's giving ✨foundation of the whole calibration stack✨ and we're obsessed.

---

🌸 NAME 🌸

gimasterbias — Creates a master bias image from a set of raw biases. that's it, that's the whole job, and she does it flawlessly 💖

---

✨ SYNOPSIS ✨

esorex gimasterbias [OPTIONS] FILE.sof

so you run her through esorex, you hand her some [OPTIONS], and you hand her a FILE.sof (a set-of-files, the little list of inputs) and she goes. no cap 🫶

---

🦋 DESCRIPTION 🦋

For detailed information please refer to the GIRAFFE pipeline user manual.

It is available at http://www.eso.org/pipelines.

tl;dr bestie: the docs live elsewhere, go read the GIRAFFE pipeline user manual for the deep lore. 😭

💅 OPTIONS 💅

here's the full menu. every single flag, no skipping, we do not gatekeep on this account 👑

• --stack-method <str> — the stacking method, i.e. how she smushes all your frames together. pick one of average, median, minmax or ksigma (that's a str; default: ´average´). the full name of this option for the EsoRex configuration file is giraffe.stacking.method [default = average].
• --stack-ksigmalow <float> — lower threshold multiplier for method ksigma (a float; default: 5.0). the full name of this option for the EsoRex configuration file is giraffe.stacking.ksigma.low [default = 5.0].
• --stack-ksigmahigh <float> — upper threshold multiplier for method ksigma (a float; default: 5.0). the full name of this option for the EsoRex configuration file is giraffe.stacking.ksigma.high [default = 5.0].
• --stack-minreject <int> — minimum rejection level for method minmax (an int; default: 1). the full name of this option for the EsoRex configuration file is giraffe.stacking.minmax.minimum [default = 1].
• --stack-maxreject <int> — maximum rejection level for method minmax (an int; default: 1). the full name of this option for the EsoRex configuration file is giraffe.stacking.minmax.maximum [default = 1].
• --mbias-oscremove <bool> — Remove pre- and over-scan regions from the created master bias image. (a bool; default: False). the full name of this option for the EsoRex configuration file is giraffe.masterbias.overscan.remove [default = False].
• --mbias-bpxclean <bool> — Correct master bias image for bad pixels (a bool; default: False). the full name of this option for the EsoRex configuration file is giraffe.masterbias.badpixel.clean [default = False].
• --bpm-create <bool> — Create bad pixel map using a simple thresholding algorithm. (temporary!) (a bool; default: True). the full name of this option for the EsoRex configuration file is giraffe.masterbias.bpm.create [default = True].
• --bpm-factor <float> — Readout noise multiplier defining the valid range of pixel values for searching bad pixels. (a float; default: 5.0). the full name of this option for the EsoRex configuration file is giraffe.masterbias.bpm.factor [default = 5.0].
• --bpm-frac <float> — Maximum fraction of pixels which may be flagged as ´bad. If more pixels are found to be ´bad a warning is issued. (a float; default: 0.15). the full name of this option for the EsoRex configuration file is giraffe.masterbias.bpm.fraction [default = 0.15].

---

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.

ngl bestie, go run esorex --help if you wanna write your own config file with your own little defaults. she supports it 💖

Basic documentation about the EsoRex program can be found at the esorex (1) man page.

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.

The other recipes of the giraf pipeline are giframestack(7), gimasterdark(7), gimasterflat(7), giscience(7), gistandard(7), giwavecalibration(7)
