The DATA directory is divided into six subdirectories.  The data directories
(OMAG and OEFD) are further subdivided into sample rate or resolution.  The
remaining directories contain ancillary information which is useful for both
OMAG and OEFD data regardless of resolution.  Ephemeris data can be found in
the EPHEM directory, OEFD phase information and OMAG offsets can be
found in the PHASEOFF directory, OMAG and OEFD instrument status parameters
can be found in the INSTSTAT directory, and engineering parameters such as
temperatures can be found in the ENGR directory.  Also contained in the DATA
directory is the COORDS.TXT and SOFTWARE.TXT files.  These files contain
descriptions of the coordinate system and software used to process the OMAG 
and OEFD data files on this CD-ROM.
