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 3391-3450. 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. OEFD -| | - 24S (contains low resolution OEFD data files) | | - HIRES (contains high resolution OEFD data files) | | - DSPROC.TXT (specificies software used to process this dataset) | | - INST.TXT (describes the Magnetometer instrument) | | - PARM.TXT (describes the instrument and dataset parameters)
