NAME
kmos_illumination - Create a frame to correct spatial non-uniformity of flatfield
SYNOPSIS
esorex kmos_illumination [OPTIONS] FILE.sof
DESCRIPTION
This recipe creates the spatial non-uniformity calibration frame needed for all three
detectors. It must be called after the kmo_wave_cal-recipe, which generates the spectral
calibration frame needed in this recipe. As input at least a sky or flat, a master dark, a
master flat and the spatial and spectral calibration frames are required.
The created product, the illumination correction, can be used as input for kmo_std_star
and kmo_sci_red.
Input files:

OPTIONS
--used_flat_type <str>
Type (sky/lamp) of input to use: (only if 2 types in input) (str; default: ´sky´).
The full name of this option for the EsoRex configuration file is
kmos.kmos_illumination.used_flat_type [default = sky].
--imethod <str>
Method to use for interpolation: ["NN" (nearest neighbour), "lwNN" (linear weighted
nearest neighbor), "swNN" (square weighted nearest neighbor), "MS" (Modified
Shepard´s method), "CS" (Cubic spline)] (str; default: ´CS´). The full name of this
option for the EsoRex configuration file is kmos.kmos_illumination.imethod [default
= CS].
--neighborhoodRange <float>
Range (pixels) to search for neighbors (float; default: 1.001). The full name of
this option for the EsoRex configuration file is
kmos.kmos_illumination.neighborhoodRange [default = 1.001].
--range <str>
The spectral ranges to combine when collapsing the reconstructed cubes. 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.kmos_illumination.range
[default = ].
--flux <bool>
TRUE: Apply flux conservation. FALSE: otherwise (bool; default: False). The full
name of this option for the EsoRex configuration file is
kmos.kmos_illumination.flux [default = False].
--add-all <bool>
FALSE: omit 1st FLAT_SKY frame (acquisition), TRUE: don´t perform any checks, add
them all (bool; default: False). The full name of this option for the EsoRex
configuration file is kmos.kmos_illumination.add-all [default = False].
--pix_scale <float>
Change the pixel scale [arcsec]. Default of 0.2" results into cubes of 14x14pix, a
scale of 0.1" results into cubes of 28x28pix, etc. (float; default: 0.2). The full
name of this option for the EsoRex configuration file is
kmos.kmos_illumination.pix_scale [default = 0.2].
--suppress_extension <bool>
Suppress filename extension. (TRUE (apply) or FALSE (don´t apply) (bool; default:
False). The full name of this option for the EsoRex configuration file is
kmos.kmos_illumination.suppress_extension [default = False].
--b_samples <long>
The number of samples in wavelength for the reconstructed cube (long; default:
2048). The full name of this option for the EsoRex configuration file is
kmos.kmos_illumination.b_samples [default = 2048].
--b_start <float>
The lowest wavelength [um] to use when reconstructing. Derived by default,
depending on the band (float; default: -1.0). The full name of this option for the
EsoRex configuration file is kmos.kmos_illumination.b_start [default = -1.0].
--b_end <float>
The highest wavelength [um] to use when reconstructing. Derived by default,
depending on the band (float; default: -1.0). The full name of this option for the
EsoRex configuration file is kmos.kmos_illumination.b_end [default = -1.0].
--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.kmos_illumination.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.kmos_illumination.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.kmos_illumination.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.kmos_illumination.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.kmos_illumination.cmax [default = 1].
--cmin <long>

for the EsoRex configuration file is kmos.kmos_illumination.detector [default = 0].
--angle <float>
Only reduce the specified angle (float; default: 370.0). The full name of this
option for the EsoRex configuration file is kmos.kmos_illumination.angle [default =
370.0].
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.
