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.
