PVO Retarding Potential Analyzer Low Resolution Processed data.

Data are stored in single orbit ASCII files (*.TAB).
All of the data files have the same internal structure which is described
by the single format file ORPADATA.FMT. File structure characteristics
which may vary from file to file (# of records, start/stop time, etc.)
are described in the individual PDS label files (*.LBL).
