✨ UVES_CAL_MBIAS ✨

okay bestie, welcome to the uves_cal_mbias manual page — this is part of the uves recipe family and it's literally the glow-up that turns your raw bias frames into one gorgeous master bias frame. no cap. 💅

🌸 NAME 🌸

uves_cal_mbias — Creates the master bias frame 💖

🦋 SYNOPSIS 🦋

esorex uves_cal_mbias [OPTIONS] FILE.sof

✨ DESCRIPTION ✨

so the way this works: this recipe creates a master bias frame by computing the median of all the input bias frames. that's it, that's the whole vibe. 🎀

Every input frame has to have the same tag and size, and each one must be either BIAS_BLUE or BIAS_RED. no mixing, no chaos, we are not doing that today.

On blue input the recipe computes one master bias frame. On red input you get a master bias frame for each chip, because red said "why have one when you can have more" 👑

And then — the average, standard deviation and median of the master bias image(s) get written to the FITS header(s). cute, documented, iconic. ✨

💅 OPTIONS 💅

  • --clean_traps <bool> — Clean detector traps. If TRUE detector traps are interpolated. The bad pixels are replaced by the average of the nearest good pixels in the same column, or simply marked as bad. The positions of bad pixels are hard-coded (as function of UVES chip). (bool; default: False). The full name of this option for the EsoRex configuration file is uves_cal_mbias.clean_traps [default = False].
  • --dc_mask_x <int> — x-size (pixel) of the mask starting at (x,y) = (1,1) (int; default: 1). The full name of this option for the EsoRex configuration file is uves_cal_mbias.dc_mask_x [default = 1].
  • --dc_mask_y <int> — y-size (pixel) of the mask starting at (x,y) = (1,1) (int; default: 1). The full name of this option for the EsoRex configuration file is uves_cal_mbias.dc_mask_y [default = 1].
  • --debug <bool> — Whether or not to save intermediate results to local directory (bool; default: False). The full name of this option for the EsoRex configuration file is uves.debug [default = False].
  • --khigh <float> — Kappa used to clip high level values, when method is set to ´mean´ (float; default: 5.0). The full name of this option for the EsoRex configuration file is uves_cal_mbias.khigh [default = 5.0].
  • --klow <float> — Kappa used to clip low level values, when method is set to ´mean´ (float; default: 5.0). The full name of this option for the EsoRex configuration file is uves_cal_mbias.klow [default = 5.0].
  • --niter <int> — Number of kappa sigma iterations, when method is set to ´mean´ (int; default: 5). The full name of this option for the EsoRex configuration file is uves_cal_mbias.niter [default = 5].
  • --pd_compute <bool> — Determine Fixed Pattern Noise. If TRUE the Fixed Patter Noise power spectrum is determined. (as function of UVES chip). (bool; default: False). The full name of this option for the EsoRex configuration file is uves_cal_mbias.pd_compute [default = False].
  • --plotter <str> — Any plots produced by the recipe are redirected to the command specified by this parameter. The plotting command must contain the substring ´gnuplot´ and must be able to parse gnuplot syntax on its standard input. Valid examples of such a command may include ´gnuplot -persist´ and ´cat > mygnuplot$$.gp´. A finer control of the plotting options can be obtained by writing an executable script, e.g. my_gnuplot.pl, that executes gnuplot after setting the desired gnuplot options (e.g. set terminal pslatex color). To turn off plotting, set this parameter to ´no´ (str; default: ´no´). The full name of this option for the EsoRex configuration file is uves.plotter [default = no].
  • --process_chip <str> — For RED arm data process the redl, redu, or both chip(s) (str; default: ´both´). The full name of this option for the EsoRex configuration file is uves.process_chip [default = both].
  • --stack_method <str> — Method used to build master frame (str; default: ´median´). The full name of this option for the EsoRex configuration file is uves_cal_mbias.stack_method [default = median].
💡 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.
