NAME
kmo_dark - Create master dark frame & bad pixel mask
SYNOPSIS
esorex kmo_dark [OPTIONS] FILE.sof
DESCRIPTION
This recipe calculates the master dark frame.
It is recommended to provide three or more dark exposures to produce a reason- able master with
associated noise.
BASIC PARAMETERS
--pos_bad_pix_rej --neg_bad_pix_rej Bad pixels above and below defined positive/negative threshold levels
will be flagged and output to the BADPIX_DARK frame (which will go into the kmo_flat recipe). The number
of bad pixels is returned as a QC1 parameter. The two para- meters can be used to change these
thresholds.
--cmethod Following methods of frame combination are available:
* ´ksigma´ (Default)
An iterative sigma clipping. For each position all pixels in the spectrum
are examined. If they deviate significantly, they will be rejected according
to the conditions:
val > mean + stdev * cpos_rej
and
val < mean - stdev * cneg_rej
where --cpos_rej, --cneg_rej and --citer are the corresponding configuration
parameters. In the first iteration median and percentile level are used.
* ´median´
At each pixel position the median is calculated.
* ´average´
At each pixel position the average is calculated.
* ´sum´
At each pixel position the sum is calculated.
* ´min_max´
The specified number of minimum and maximum pixel values will be rejected.
--cmax and --cmin apply to this method.
--file_extensionSet this parameter to TRUE if the EXPTIME keyword should be appended to the output
filenames.

OPTIONS
--pos_bad_pix_rej <float>
The positive rejection threshold for bad pixels (float; default: 50.0). The full name of this
option for the EsoRex configuration file is kmos.kmo_dark.pos_bad_pix_rej [default = 50.0].
--neg_bad_pix_rej <float>
The negative rejection threshold for bad pixels (float; default: 50.0). The full name of this
option for the EsoRex configuration file is kmos.kmo_dark.neg_bad_pix_rej [default = 50.0].
--file_extension <bool>
Controls if EXPTIME keyword should be appended to product filenames. (bool; default: False). The
full name of this option for the EsoRex configuration file is kmos.kmo_dark.file_extension
[default = False].
--cmethod <str>
Either apply "average", "median", "sum", "min_max." or "ksigma". (str; default: ´ksigma´). The
full name of this option for the EsoRex configuration file is kmos.kmo_dark.cmethod [default =
ksigma].
--cpos_rej <float>
The positive rejection threshold for kappa-sigma-clipping (sigma). (float; default: 3.0). The
full name of this option for the EsoRex configuration file is kmos.kmo_dark.cpos_rej [default =
3.0].
--cneg_rej <float>
The negative rejection threshold for kappa-sigma-clipping (sigma). (float; default: 3.0). The
full name of this option for the EsoRex configuration file is kmos.kmo_dark.cneg_rej [default =
3.0].
--citer <long>
The number of iterations for kappa-sigma-clipping. (long; default: 3). The full name of this
option for the EsoRex configuration file is kmos.kmo_dark.citer [default = 3].
--cmax <long>
The number of maximum pixel values to clip with min/max-clipping. (long; default: 1). The full
name of this option for the EsoRex configuration file is kmos.kmo_dark.cmax [default = 1].
--cmin <long>
The number of minimum pixel values to clip with min/max-clipping. (long; default: 1). The full
name of this option for the EsoRex configuration file is kmos.kmo_dark.cmin [default = 1].
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.
