Detailed Description

Author
Peter Weilbacher
  Processing handles each raw input image separately: it trims the raw
  data and records the overscan statistics, subtracts the bias (taking
  account of the overscan, if --overscan is not "none"), optionally
  detects cosmic rays (note that by default cosmic ray rejection is
  handled in the post processing recipes while the data is reformatted
  into a datacube, so that the default setting is cr="none" here),
  converts the images from adu to count, subtracts the dark, divides by
  the flat-field, and (optionally) propagates the integrated flux value
  from the twilight-sky cube.



  The reduced image is then saved (if --saveimage=true).

  The input calibrations geometry table, trace table, and wavelength
  calibration table are used to assign 3D coordinates to each CCD-based
  pixel, thereby creating a pixel table for each exposure.

  If --skylines contains one or more wavelengths for (bright and isolated)
  sky emission lines, these lines are used to correct the wavelength
  calibration using an offset.

  The data is then cut to a useful wavelength range (if --crop=true).

  If an ILLUM exposure was given as input, it is then used to correct the
  relative illumination between all slices of one IFU. For this, the data
  of each slice is multiplied by the normalized median flux of that slice
  in the ILLUM exposure.

  As last step, the data is divided by the normalized twilight cube (if
  given), using the 3D coordinate of each pixel in the pixel table to
  interpolate the twilight correction onto the data.

  This pre-reduced pixel table for each exposure is then saved to disk.
