NAME

vimos_ima_dark - Dark combination for imaging

SYNOPSIS

esorex vimos_ima_dark [OPTIONS] FILE.sof

DESCRIPTION

vimos_ima_dark -- VIMOS dark combine recipe.

Combine a list of dark frames into a mean dark frame. Optionally compare the output frame to a reference dark frame

The program accepts the following files in the SOF:

Tag Description

DARK A list of raw dark images
MASTER_BIAS A master bias frame
REFERENCE_DARK Optional reference dark frame
MASTER_BPM Optional master bad pixel map or
MASTER_CONF Optional master confidence map If no reference dark frame is made available, then no comparison will be done. This means there will be no output difference image and no stats tableIf neither a master bad pixel map nor confidence map is provided then thestats will be done assuming all pixels are good

OPTIONS

--combtype <str>

Combination algorithm (str; default: ´median´). The full name of this option for the EsoRex configuration file is vimos.vimos_ima_dark.combtype [default = median].

--scaletype <str>

Scaling algorithm (str; default: ´exptime´). The full name of this option for the EsoRex configuration file is vimos.vimos_ima_dark.scaletype [default = exptime].

--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_dark.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_dark.thresh [default = 5.0].

--ncells <int>

Number of cells for diff image stats (int; default: 8). The full name of this option for the EsoRex configuration file is vimos.vimos_ima_dark.ncells [default = 8].

--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_dark.prettynames [default = False].

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.
