NAME
kmo_make_image - Collapse a cube to create a spatial image
SYNOPSIS
esorex kmo_make_image [OPTIONS] FILE.sof
DESCRIPTION
This recipe collapses a cube along the spectral axis using rejection. By default all spectral slices are
averaged.
Errors are propagated for the same spectral ranges as for the input data if a noise map is provided.
BASIC PARAMETERS
--range The spectral range can be delimited to one or several sub-ranges like "1.8,1.9" or "1.8,1.9;
2.0,2.11"
--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 wished 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 min and max pixel values will be rejected.
--cmax and --cmin apply to this method.
ADVANCED PARAMETERS
--threshold Optionally an OH spectrum can be provided. In this case a threshold can be defined. The
wavelengths of values above the threshold level in the OH spectrum are omitted in the input frame. This
parameter can be combined with the --range parameter. Negative threshold values are ignored.
Own spectra can be converted into the required F1S KMOS FITS format for the OH spectrum using
kmo_fits_stack.

OPTIONS
--range <str>
The spectral ranges to combine. e.g."x1_start,x1_end;x2_start,x2_end" (microns) (str; default:
´´). The full name of this option for the EsoRex configuration file is kmos.kmo_make_image.range
[default = ].
--threshold <float>
The OH threshold level (%) (float; default: 0.1). The full name of this option for the EsoRex
configuration file is kmos.kmo_make_image.threshold [default = 0.1].
--cmethod <str>
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_make_image.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_make_image.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_make_image.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_make_image.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_make_image.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_make_image.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.
