This directory contains a single file (CATALOG.CAT) which contains all of
the metadata associated with this CD-ROM. The metadata is organized into
heirarchical templates which can be loaded into a relational database. The
component templates have been arranged in this file from the most general to 
most specific, thus the first portion of the file contains
mission and spacecraft related metadata; next are the seven instrument 
description templates; and then the coordinate, dataset, dataset 
processing, parameter, and software templates for each of the instruments.
