NAME
uves_obs_redchain - Runs the full UVES reduction chain
SYNOPSIS
esorex uves_obs_redchain [OPTIONS] FILE.sof
DESCRIPTION
This recipe does a complete science reduction. It runs all necessary calibration recipes depending on the
availability of raw/processed calibration frames.
Input frames are all UVES raw and reference frames: formatchecks, ARC_LAMP_FORM_xxxx, xxxx=BLUE or RED,
order definition frames, ORDER_FLAT_xxx, biases, BIAS_xxx, darks, DARK_xxx, flats, FLAT_xxx, arc lamps,
ARC_LAMP_xxx, standard stars, STANDARD_xxx a wavelength catalogue table,LINE_REFER_TABLE, and optionally
a wavelength table of bright lines,LINE_INTMON_TABLE, used only for computing Quality Control parameters.
a reference standard star flux table, FLUX_STD_TABLE, a table describing the atmospheric
extintion,EXTCOEFF_TABLE.
optionally, science frames, SCIENCE_xxx, or UVES_SCI_POINT_xxx, or UVES_SCI_EXTND_xxx, or
UVES_SCI_SLICER_xxx.
For further details on the data reduction and the input frame types refer to the man page of the
individual recipes.

configuration file is uves_obs_redchain.uves_obs_scired.reduce.objoffset [default = 0.0].
--uves_obs_scired.reduce.objslit <float>
Object window size (in pixels), ignored for optimal extraction. The value must be smaller than the
total slit length. If negative, the default value (half of full slit length) is used. The upper
and lower sky windows are defined as the part of the full slit (if any) outside the object window.
The center of the object window is determined by the offset parameter. (float; default: -1.0). The
full name of this option for the EsoRex configuration file is
uves_obs_redchain.uves_obs_scired.reduce.objslit [default = -1.0].
--uves_obs_scired.reduce.rebin.scale <bool>
Whether or not to multiply by the factor dx/dlambda (pixels per wavelength) during the rebinning
to conserve the flux. This option is disabled as default because applying the flat field
correction already ensures flux conservation. Therefore this parameter should be TRUE (for
response and science data) only if reduce.ffmethd = no. (bool; default: False). The full name of
this option for the EsoRex configuration file is
uves_obs_redchain.uves_obs_scired.reduce.rebin.scale [default = False].
--uves_obs_scired.reduce.rebin.wavestep <float>
The bin size used for BLUE/REDL data (in w.l.u.) in wavelength space. If negative, a step size of
2/3 * ( average pixel size ) is used. (float; default: -1.0). The full name of this option for
the EsoRex configuration file is uves_obs_redchain.uves_obs_scired.reduce.rebin.wavestep [default
= -1.0].
--uves_obs_scired.reduce.rebin.wavestep_redu <float>
The bin size used for REDU data (in w.l.u.) in wavelength space. If negative, a step size of 2/3 *
( average pixel size ) is used. (float; default: -1.0). The full name of this option for the
EsoRex configuration file is uves_obs_redchain.uves_obs_scired.reduce.rebin.wavestep_redu [default
= -1.0].
--uves_obs_scired.reduce.skysub <bool>
Do sky-subtraction (only applicable to linear and average extractions)? (bool; default: True). The
full name of this option for the EsoRex configuration file is
uves_obs_redchain.uves_obs_scired.reduce.skysub [default = True].
--uves_obs_scired.reduce.slitlength <float>
Extraction slit length (in pixels). If negative, the value inferred from the raw frame header is
used (float; default: -1.0). The full name of this option for the EsoRex configuration file is
uves_obs_redchain.uves_obs_scired.reduce.slitlength [default = -1.0].
--uves_obs_scired.reduce.tiltcorr <bool>
If enabled (recommended), the provided dispersion solutions obtained at different slit positions
are interpolated linearly at the actually measured position of the object/sky. Line tilt
correction is currently not supported for 2d extraction, in which case the dispersion solution
obtained at the middle of the slit is always used. (bool; default: True). The full name of this
option for the EsoRex configuration file is uves_obs_redchain.uves_obs_scired.reduce.tiltcorr
[default = True].
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.
