GIMASTERBIAS(7) giraf recipes GIMASTERBIAS(7)

NAME

gimasterbias - Creates a master bias image from a set of raw biases.

SYNOPSIS

esorex gimasterbias [OPTIONS] FILE.sof

DESCRIPTION

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

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

OPTIONS

Stacking method: average, median, minmax or ksigma (str; default: ´average´). The full name of this option for the EsoRex configuration file is giraffe.stacking.method [default = average].
Lower threshold multiplier for method ksigma (float; default: 5.0). The full name of this option for the EsoRex configuration file is giraffe.stacking.ksigma.low [default = 5.0].
Upper threshold multiplier for method ksigma (float; default: 5.0). The full name of this option for the EsoRex configuration file is giraffe.stacking.ksigma.high [default = 5.0].
Minimum rejection level for method minmax (int; default: 1). The full name of this option for the EsoRex configuration file is giraffe.stacking.minmax.minimum [default = 1].
Maximum rejection level for method minmax (int; default: 1). The full name of this option for the EsoRex configuration file is giraffe.stacking.minmax.maximum [default = 1].
Remove pre- and over-scan regions from the created master bias image. (bool; default: False). The full name of this option for the EsoRex configuration file is giraffe.masterbias.overscan.remove [default = False].
Correct master bias image for bad pixels (bool; default: False). The full name of this option for the EsoRex configuration file is giraffe.masterbias.badpixel.clean [default = False].
Create bad pixel map using a simple thresholding algorithm. (temporary!) (bool; default: True). The full name of this option for the EsoRex configuration file is giraffe.masterbias.bpm.create [default = True].
Readout noise multiplier defining the valid range of pixel values for searching bad pixels. (float; default: 5.0). The full name of this option for the EsoRex configuration file is giraffe.masterbias.bpm.factor [default = 5.0].
Maximum fraction of pixels which may be flagged as ´bad. If more pixels are found to be ´bad a warning is issued. (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.
