Notes on Using the Index Tables                                               
                                                                              
The index and cumulative index tables in this directory contain at            
least one row (record) for each Lunar Prospector MAG/ER data product          
on the present disk. Most of the index tables contain records for             
data products on this volume. The CUMINDEX.TAB file is a cumulative           
index for data products on all previous volumes in the series and on          
the present volume.  All tables are formatted so that they can be read        
directly into many data management systems or spreadsheet programs.  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 table to be        
treated as a fixed length record file on computers that support this          
file type and as a normal text file on other computers.                       
                                                                              
Each index file has a PDS label file that describes the content               
and structure of the fields in the table, including field name,               
format, and description.  The values for start byte and number of             
bytes listed in the label file do not include commas between fields or        
quotation marks surrounding character fields.                                 
                                                                              
The manifest files (MANIFEST.TAB and CUMMANIF.TAB) are like index             
files, but they list every file on the disk instead of just the               
MAG/ER data files.
