    The MAGER directory contains the Magnetometer/Electron
Reflectometer (MAG/ER) data and ancillary data.  There is a
subdirectory for each of the original CD-ROM volumes that archived
this MAG/ER data.  The subdirectory names have the form MGERnnnn where
nnnn is the last four digits of the original CD-ROM volume_id.  These
subdirectories are further divided as shown below:


  ANCIL       Contains ancillary data pertaining to the spacecraft,
              in the form of kernel files.

  ER          Contains data from the Electron Reflectometer (ER).

  MAG         Contains data from the Magnetometer (MAG), in
   |          2 subdirectories:
   |
   +- SUNSTATE     Contains MAG data expressed in Sun-State (SS)
   |               coordinates.
   |
   +- PCENTRIC     Contains MAG data expressed in Planetocentric (PC)
                   coordinates.
