Collapse a cube to create a spatial image
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.

MAKE_IMAGE F2I Collapsed data cubes
Create an object for the recipe kmo_make_image.
import cpl
kmo_make_image = cpl.Recipe("kmo_make_image")
The spectral ranges to combine. e.g.”x1_start,x1_end;x2_start,x2_end” (microns) (str; default: ‘’) [default=”“].
The OH threshold level (%) (float; default: 0.1) [default=0.1].
Apply “average”, “median”, “sum”, “min_max.” or “ksigma”. (str; default: ‘ksigma’) [default=”ksigma”].
The positive rejection threshold for kappa-sigma-clipping (sigma). (float; default: 3.0) [default=3.0].
The negative rejection threshold for kappa-sigma-clipping (sigma). (float; default: 3.0) [default=3.0].
The number of iterations for kappa-sigma-clipping. (long; default: 3) [default=3].
The number of maximum pixel values to clip with min/max-clipping. (long; default: 1) [default=1].
The number of minimum pixel values to clip with min/max-clipping. (long; default: 1) [default=1].
The following code snippet shows the default settings for the available parameters.
import cpl
kmo_make_image = cpl.Recipe("kmo_make_image")
kmo_make_image.param.range = ""
kmo_make_image.param.threshold = 0.1
kmo_make_image.param.cmethod = "ksigma"
kmo_make_image.param.cpos_rej = 3.0
kmo_make_image.param.cneg_rej = 3.0
kmo_make_image.param.citer = 3
kmo_make_image.param.cmax = 1
kmo_make_image.param.cmin = 1
You may also set or overwrite some or all parameters by the recipe parameter param, as shown in the following example:
import cpl
kmo_make_image = cpl.Recipe("kmo_make_image")
[...]
res = kmo_make_image( ..., param = {"range":"", "threshold":0.1})
