# kmo\_make\_image(7)

Collapse a cube to create a spatial image

## 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.

\--cpos\_rej --cneg\_rej --citer\

    see --cmethod=´min\_max´

## 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** *\<int\>*

  The number of iterations for kappa-sigma-clipping. (int; default: 3). The full name of this option for the EsoRex configuration file is **kmos.kmo\_make\_image.citer** \[default = *3*\].

- **--cmax** *\<int\>*

  The number of maximum pixel values to clip with min/max-clipping. (int; default: 1). The full name of this option for the EsoRex configuration file is **kmos.kmo\_make\_image.cmax** \[default = *1*\].

- **--cmin** *\<int\>*

  The number of minimum pixel values to clip with min/max-clipping. (int; 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.
