The INDEX directory contains an index table, INDEX.TAB, that lists
every data product in the archive. The index table is accompanied by a
PDS label, INDEX.LBL, that describes the format of the table.

The index table is an ASCII text file. Each line (record) in INDEX.TAB
contains information about a data product in the archive. The record
includes the path and file name of the PDS label that describes the
data product. 

Each line in INDEX.TAB consists of a set of fixed-length fields
delimited by commas. INDEX.LBL tells the start byte, number of bytes,
and data type of each field. Character fields are enclosed in double
quotation marks (").

The INDEX directory also contains a browse index table, BROWINDX.TAB every 
browse product in the archive. The browse index table is accompanied by a
PDS label, BROWINDX.TAB, that describes the format of the table.

The browse index table is an ASCII text file. Each line (record) in 
BROWINDX.TAB contains information about a browse product in the archive. 
The record includes the path and file name of the PDS label that describes 
the browse product. 

Each line in BROWINDX.TAB consists of a set of fixed-length fields
delimited by commas. BROWINDX.LBL tells the start byte, number of bytes,
and data type of each field. Character fields are enclosed in double
