NAME
muse_lsf - Compute the LSF
SYNOPSIS
esorex muse_lsf [OPTIONS] FILE.sof
DESCRIPTION
Compute the slice and wavelength dependent LSF from a lines spectrum (ARC lamp).
OPTIONS
--nifu <int>
IFU to handle. If set to 0, all IFUs are processed serially. If set to -1, all IFUs
are processed in parallel. (int; default: 0). The full name of this option for the
EsoRex configuration file is muse.muse_lsf.nifu [default = 0].
--overscan <str>
If this is "none", stop when detecting discrepant overscan levels (see ovscsigma),
for "offset" it assumes that the mean overscan level represents the real offset in
the bias levels of the exposures involved, and adjusts the data accordingly; for
"vpoly", a polynomial is fit to the vertical overscan and subtracted from the whole
quadrant. (str; default: ´vpoly´). The full name of this option for the EsoRex
configuration file is muse.muse_lsf.overscan [default = vpoly].
--ovscreject <str>
This influences how values are rejected when computing overscan statistics. Either
no rejection at all ("none"), rejection using the DCR algorithm ("dcr"), or
rejection using an iterative constant fit ("fit"). (str; default: ´dcr´). The full
name of this option for the EsoRex configuration file is muse.muse_lsf.ovscreject
[default = dcr].
--ovscsigma <float>
If the deviation of mean overscan levels between a raw input image and the
reference image is higher than |ovscsigma x stdev|, stop the processing. If
overscan="vpoly", this is used as sigma rejection level for the iterative
polynomial fit (the level comparison is then done afterwards with |100 x stdev| to
guard against incompatible settings). Has no effect for overscan="offset". (float;
default: 30.0). The full name of this option for the EsoRex configuration file is
muse.muse_lsf.ovscsigma [default = 30.0].
--ovscignore <int>
The number of pixels of the overscan adjacent to the data section of the CCD that
are ignored when computing statistics or fits. (int; default: 3). The full name of
this option for the EsoRex configuration file is muse.muse_lsf.ovscignore [default
= 3].
--save_subtracted <bool>
Save the pixel table after the LSF subtraction. (bool; default: False). The full
name of this option for the EsoRex configuration file is
muse.muse_lsf.save_subtracted [default = False].
--line_quality <int>
Minimal quality flag in line catalog for selection (int; default: 3). The full name
of this option for the EsoRex configuration file is muse.muse_lsf.line_quality
[default = 3].
--lsf_range <float>
Wavelength window (half size) around each line to estimate LSF (float; default:
7.5). The full name of this option for the EsoRex configuration file is
muse.muse_lsf.lsf_range [default = 7.5].
--lsf_size <int>
Image size in LSF direction (int; default: 150). The full name of this option for
the EsoRex configuration file is muse.muse_lsf.lsf_size [default = 150].
--lambda_size <int>
Image size in line wavelength direction (int; default: 30). The full name of this
option for the EsoRex configuration file is muse.muse_lsf.lambda_size [default =
30].
--lsf_regression_window <float>
Size of the regression window in LSF direction (float; default: 0.7). The full name
of this option for the EsoRex configuration file is
muse.muse_lsf.lsf_regression_window [default = 0.7].
--merge <bool>
Merge output products from different IFUs into a common file. (bool; default:
False). The full name of this option for the EsoRex configuration file is
muse.muse_lsf.merge [default = False].
--combine <str>
Type of lampwise image combination to use. (str; default: ´sigclip´). The full name
of this option for the EsoRex configuration file is muse.muse_lsf.combine [default
= sigclip].
--method <str>
LSF generation method. Depending on this value, either an interpolated LSF cube is
created, or a table with the parameters of a hermitean gaussian. (str; default:
´interpolate´). The full name of this option for the EsoRex configuration file is
muse.muse_lsf.method [default = interpolate].
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.
