1. Introduction                                                               
                                                                              
This document provides an overview of the Near Earth Asteroid                 
Rendezvous X-Ray Level 2 document archive.  Thes documents                    
describe the design, development, implementation, calibration                 
and operations of the NEAR XRS instrument.  The directory                     
contains references for 2 documents that could not be included                
in this archive due to copyright concerns and are cited in the                
REF.CAT file in the CATALOG directory.                                        
                                                                              
The included document XRS_REQS_7_2.DOC was originally developed               
using Microsoft Word Office 2000 and contains a  significant                  
number of specialized equations, graphs, tables, and figures.  The            
WORD format is unfortunately not directly supported by the PDS                
due to the (Word) format's proprietary status.  Several versions              
of this document have been generated in alternative formats to                
preserve the integrity of the information contained within the                
document.
