esorex vmifuscience [OPTIONS] FILE.sof

This recipe extracts IFU scientific 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 eventually corrected for the relative differences in transmission from fiber to fiber.

Output files:

  DO category:             Data type:  Explanation:
  IFU_SCIENCE_REDUCED      FITS image  Reduced scientific spectra
  IFU_SCIENCE_FLUX_REDUCED FITS image  Reduced scientific spectra
  IFU_FOV                  FITS image  Reconstructed IFU field-of-view
  IFU_SKY_TRACE            FITS table  Science aligned extraction mask

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.

For more details, please refer to the VIMOS Pipeline User\'s Guide.

--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].

--ApplyTransmission <bool>

Apply transmission correction to extracted scientific spectra (bool; default: True). The full name of this option for the EsoRex configuration file is vimos.Parameters.apply.transmission [default = True].

--CalibrateFlux <bool>

Extracted spectra are flux calibrated. (bool; default: False). The full name of this option for the EsoRex configuration file is vimos.Parameters.flux.calibration [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].

--UseSkyIndividual <bool>

Use sky lines to refine the wavelength calibration individually for each spectrum (bool; default: False). The full name of this option for the EsoRex configuration file is vimos.Parameters.sky.individual [default = False].

--ComputeQC <bool>

Compute QC1 parameters (bool; default: False). The full name of this option for the EsoRex configuration file is vimos.Parameters.quality.enable [default = False].

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.
