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.
