Help for HRFILL


  This program changes the DN value of all pixels which were flaged as bad
  during the calibration process.

  A pixel can be flaged as "bad" due to several reasons:
    - The pixel was saturated.
    - The pixel has a physical defect (aka blemish pixel).
    - The pixel value was lost during compression or transmission.

  HRFILL tries to fill the pixels with useful values:
    - Maximum_of_valid_pixels+1 for the saturated pixels
    - Median of the surrounding valid pixels otherwise

  HRFILL updates the VICAR label keyword OVERFLOW_VALUE with the new value of
  the saturated pixels ("Maximum_of_valid_pixels+1").
