The OEFD directory is divided into two subdirectories.  These directories
(24S and HIRES) contain either 2 spin period averages with data output on
single spin period centers (approximately 24 second averages with data output
approximately every 12 seconds) or full resolution data for orbits 2761 - 2830.
Data are organized into single orbit files which follow the naming convention:
ORBxxxx.FFD where xxxx is a four digit orbit number. In addition, for each data
file there is a header file ORBxxxx.FFH, a label file which describes the file
characteristics, such as number of records, record length, etc. called
ORBxxxx.LBL.  Also contained in the OEFD directory are the files DSPROC.TXT,
INST.TXT and PARM.TXT which are descriptions. The DSPROC.TXT maps data
processing software to PDS datasets, the INST.TXT describes the OEFD instrument
and the PARM.TXT describes the measured and derived parameters of the OEFD
experiment.  In addition, each file has a .LBL file which describes the file
characteristics.  A file called CATALOG.CAT in the CATALOG directory contains
all of the PDS catalog templates on this CD-ROM.
