NAME
kmo_reconstruct - Performs the cube reconstruction using different interpolation methods.
SYNOPSIS
esorex kmo_reconstruct [OPTIONS] FILE.sof
DESCRIPTION
Data with or without noise is reconstructed into a cube using the calibration frames XCAL,
YCAL and LCAL. XCAL and YCAL are generated using recipe kmo_flat, LCAL is generated using
recipe kmo_wave_cal.
The input data can contain noise extensions and will be reconstructed into additional
extensions.
If an OH spectrum is given in the SOF file the lambda axis will be corrected using the OH
lines as reference.
BASIC PARAMETERS
--imethod The interpolation method used for reconstruction.
--detectorimage Specify if the resampled image of the input frame should be generated.
There- fore all slitlets of all IFUs are aligned one next to the other. This frame serves
for quality control. One can immediately see if the reconstruction was successful.
--file_extensionSet to TRUE if OBS_ID (from input frame header) should be appended to the
output frame.
ADVANCED PARAMETERS
--flux Specify if flux conservation should be applied.
--neighborhoodRange Defines the range to search for neighbors during reconstruction
--b_samples The number of samples in spectral direction for the reconstructed cube. Ideal-
ly this number should be greater than 2048, the detector size.
--b_start --b_end Used to define manually the start and end wavelength for the
reconstructed cube. By default the internally defined values are used.
--pix_scale 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.
--xcal_interpolation If TRUE interpolate the pixel position in the slitlet (xcal) using
the two closest rotator angles in the calibration file. Otherwise take the values of the
closest rotator angle

OPTIONS
--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.kmo_reconstruct.imethod [default =
CS].
--neighborhoodRange <float>
Defines the range to search for neighbors. in pixels (float; default: 1.001). The
full name of this option for the EsoRex configuration file is
kmos.kmo_reconstruct.neighborhoodRange [default = 1.001].
--flux <bool>
TRUE: Apply flux conservation. FALSE: otherwise (bool; default: False). The full
name of this option for the EsoRex configuration file is kmos.kmo_reconstruct.flux
[default = False].
--detimg <bool>
TRUE: if resampled detector frame should be created, FALSE: otherwise (bool;
default: False). The full name of this option for the EsoRex configuration file is
kmos.kmo_reconstruct.detectorimage [default = False].
--file_extension <bool>
TRUE: if OBS_ID keyword should be appended to output frames, FALSE: otherwise
(bool; default: False). The full name of this option for the EsoRex configuration
file is kmos.kmo_reconstruct.file_extension [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.kmo_reconstruct.pix_scale [default = 0.2].
--dev_flip <bool>
INTENDED FOR PIPELINE DEVELOPERS ONLY: Set this parameter to TRUE if the
wavelengths are ascending on the detector from bottom to top (only for old
simulation data). (bool; default: False). The full name of this option for the
EsoRex configuration file is kmos.kmo_reconstruct.dev_flip [default = False].
--xcal_interpolation <bool>
TRUE: Interpolate xcal between rotator angles. FALSE: otherwise (bool; default:
True). The full name of this option for the EsoRex configuration file is
kmos.kmo_reconstruct.xcal_interpolation [default = True].
--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.kmo_reconstruct.b_samples [default = 2048].
--b_start <float>
The lowest wavelength [um] to take into account when reconstructing (default of -1
sets the proper value for the actual band automatically) (float; default: -1.0).
The full name of this option for the EsoRex configuration file is
kmos.kmo_reconstruct.b_start [default = -1.0].
--b_end <float>
The highest wavelength [um] to take into account when reconstructing (default of -1
sets the proper value for the actual band automatically) (float; default: -1.0).
The full name of this option for the EsoRex configuration file is
kmos.kmo_reconstruct.b_end [default = -1.0].
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.
