     This file contains a description of the index tables created for the     
IHW addenda data submitted to the Small Bodies Node.   For those missions/    
experiments for which a large number of files were archived, a separate table 
was created and placed into this directory designated by the experiment code. 
The index tables carry information about the scientific parameters for the    
experiment.  To locate any file on the CDROM use INDEX which identifies       
the filename (with path), and size.  The other scientific index files are     
given as chronological listings.                                              
                                                                              
     For the NNSN data, the index file NEARINDX.TAB for the submitted         
data on HAL_0021 has been copied to the current volume and edited to          
reflect only the corrected comet Halley data.  The detached label             
has the description modified to reflect that the current CD-ROM               
actually has the replacement files.   The modified label follows              
current PDS standards.   In addition, the NNSNINDEX.TAB is similar to the     
other data.  Finally the ICE ICI data consists of two mass ranges designated  
as low (a) or high (b) mass.    The chronological order of files in the index 
table is kept, i.e., the mass ranges are not separated into individual        
subdirectories.                                                               
                                                                              
     There are two types of files in each subdirectory, distinguished         
by the extensions on the file names. The filenames themselves identify        
the experiment which was used to produce each index. The types of files       
are:                                                                          
                                                                              
        *.LBL - These are PDS labels describing the data tables.  They already
                contain pointers to the data tables, so no further steps are  
                required to make them accessible to PDS table-processing      
                software.                                                     
                                                                              
                                                                              
        *.TAB - These files contain the actual metadata records from each     
                file.  They are ASCII tables and each line ends with the      
                characters <CR><LF> (ASCII 13 and 10 respectively). All fields
                in the tables are fixed width.
