The INDEX directory contains index tables that list every TER and TER BROWSE 
data product in the archive. The index tables are organized by month and are 
of the form TERyymm_INDEX.TAB and TERyymm_BRINDEX.TAB, respectively. Each 
index table is accompanied by a PDS label, TERyymm_INDEX.LBL or 
TERyymm_BRINDEX.LBL, that describes the format of the table. When a month is 
split across volumes, the DOY range is appended to the index table name 
(e.g., TER0808_214_221_INDEX.TAB contains a list of TERs from DOY 214 
through 221 in August 2008. August 2008 TERs for DOY 222+ can be found on 
the next volume in TER0808_222_244_INDEX.TAB).

The index tables are ASCII text files. Each line (record) in a table
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 a .TAB file consists of a set of fixed-length fields
delimited by commas. The associated .LBL file tells the start byte,
number of bytes, and data type of each field. Character fields are
enclosed in double quotation marks (").
