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 1331 - 1400.
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.
