NAME
vmifustandard - Extract a standard star spectrum.
SYNOPSIS
esorex vmifustandard [OPTIONS] FILE.sof
DESCRIPTION
This recipe extracts IFU standard star fiber spectra using the input
extraction mask, after aligning it to the brightest fiber spectra
detected on the input exposure. The extracted spectra are then
resampled at a constant wavelength step, after aligning the input
wavelength calibration to the positions of a set of identified sky
lines. The extracted spectra are finally corrected for the relative
differences in transmission from fiber to fiber, and summed together.

Output files:
DO category: Data type: Explanation:
IFU_STANDARD_REDUCED FITS image Reduced standard star spectra
IFU_FOV FITS image Reconstructed field-of-view image
IFU_STANDARD_EXTRACTED FITS table Total standard star spectrum
IFU_SCIENCE_SKY FITS table Total sky spectrum
IFU_SPECPHOT_TABLE FITS table Efficiency and response curves
The extraction mask, the wavelength calibration, and the relative
transmission table, are those generated by the recipe vmifucalib. A CCD
table must be specified only if a bad pixel cleaning is requested.
The spectra extracted from the fibers on the standard star are added
and compared to the catalog fluxes of the same star, to obtain the
efficiency curve and the response curve to use for flux calibration.
The procedure is the same as the one applied in the case of MOS data,
by recipe vmmosstandard.
OPTIONS
--BiasMethod <str>
Bias removal method. (str; default: Zmaster). The full name of
this option for the EsoRex configuration file is
vimos.Parameters.bias.removing.method [default = Zmaster].
--CleanBadPixel <bool>
Bad pixel correction on master flat field. (bool; default:
False). The full name of this option for the EsoRex
configuration file is vimos.Parameters.badpixel.clean [default =
False].
--UseSkylines <bool>
Use sky lines to refine the wavelength calibration (bool;
default: True). The full name of this option for the EsoRex
configuration file is vimos.Parameters.sky.align [default =
True].
--ResponseOrder <long>
Order of the polynomial used to smooth the instrument response
curve. (long; default: 5). The full name of this option for the
EsoRex configuration file is vimos.Parameters.response.order
[default = 5].
--ReduceAnyFrame <bool>
Reduce any frame. (bool; default: False). The full name of this
option for the EsoRex configuration file is
vimos.Parameters.reduceall [default = False].
--ComputeQC <bool>
Compute QC1 parameters (bool; default: True). The full name of
this option for the EsoRex configuration file is
vimos.Parameters.quality.enable [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.
