      The CALIB directory contains the calibrations files used in the processing
of the raw data or needed to use the data products on the volume.
                                                                              
     Each object is in ASCII; the files have a fixed length of
characters per line, but this fixed length can differ from file to file. The
details and correct values can be found in the label header of each file. Each
line is delimited with a carriage-return (ASCII 13) line-feed (ASCII 10) pair.

                                                                              
     Structure of the CALIB directory:

  |- UPLINK_FREQ_CORRECT
  |                       This folder will only be generated if the
  |                       uplink frequency in one of the .RAW
  |                       files was identified as wrong.
  |                       The files in the folder tells the user which files 
  |                       were affected and where to find the corrected
  |                       Level 2 data files.
