                    INDEX Directory Contents

     The INDEX directory contains the files INDEX.TAB, a table that
lists every data file on the archive volume, INDEX.HTM, an HTML version
of INDEX.TAB, and INDEX.LBL, a detached PDS label that describes both
INDEX.TAB and INDEX.HTM.  

     INDEX.TAB contains one row (record) for each data product on the
volume. Each row contains several columns (fields) that describe the
data product: the product ID, the directory and file name, the product
creation date, the data acquisition date, the lunar feature targeted
by the observation, the latitude and longitude of the observation, and
a data quality indicator. The rows are in alphabetical order by feature
name.

     The table is formatted so that it can be read directly into many
data management systems.  All fields are separated by commas, and
character fields are enclosed in double quotation marks (").
Character fields are left justified, and numeric fields are right
justified.  Each record ends with ASCII carriage return and line feed
characters.  This allows the file to be read by various computer 
operating systems.

     INDEX.HTM is an HTML version of INDEX.TAB provided for ease of
access to the data using a Web browser. To begin browsing the data,
open INDEX.HTM in any Web browser. The Web page has the same
information found in INDEX.TAB, with column headings added.  It
includes hyperlinks to the individual data files.

     INDEX.LBL is a PDS label for both INDEX.TAB and INDEX.HTM. It has
a description of the content and structure of the fields in
INDEX.TAB. This description includes the name of each field, its
format, and a brief definition.  The values listed for start byte and
number of bytes do not include commas between fields or quotation
marks surrounding character fields. Note that the column formatting
information applies only to INDEX.TAB, not to INDEX.HTM.
