The low resolution data are stored in single orbit ASCII data files which have
been organized into 100 orbit subdirectories.

UADS data was the original data product delivered, but the header records were
stripped out and a time column replaces the original 3 columns (time fields)
to make them flat tables with PDSTIME. The header information is in a file
called UADS_HDR.TXT. The original UADS data can be obtained from the PDS/PPI
node.

The /DATA directory contains a description of the ORPA instrument and dataset.
The /DOCUMENT directory contains full reproductions of all these documents.

The PDS catalog templates associated with this dataset are located in the
CATALOG directory off the root of this CD-ROM in the file called "*.CAT".
