CONTENTS OF THE DATA DIRECTORY

The DATA directory contains CRaTER data product files, their detached PDS
labels, and the processing logs that detailed their creation. These are
arranged in two levels of subdirectory:

yyyy
    A directory containing all CRaTER products from data recorded in the
    year "yyyy", e.g., "2009".

yyyy/yyyyddd
    "yyyyddd" is a subdirectory of the "yyyy" directory. It contains all
    CRaTER products from data recorded in day "ddd" of year "yyyy". Day
    "001" is January 1, and the CRaTER data in this directory will span
    the epoch from 00:00:00 UTC through 23:59:59.9999 UTC on that day.

Within each "yyyy/yyyyddd" subdirectory, some or all of the following
files are to be found. In these file names, "yyyyddd" is identical to the
subdirectory name, and "nn" is the product version number which starts at
"01" for the first version and increments by one if the product is
reprocessed.
