Contains a text description of the contents of the DOCUMENT subdirectory which
contains an INSTRUMENT and MISSION subdirectory. Contains a text description  
of the NEAR data archive plan. The data file parameter definitions are in     
/DOCUMENT/INSTRUMENT/{GRB,GRF,GRS,XRF,XRS}DEFINITIONS.TXT file.               
                                                                              
The INSTRUMENT subdirectory contains an instrument definitions text           
file, which describes the instrument and data points found in the data files. 
It also contains a CALPAPER subdirectory which is an empty placeholder for the
instrument calibration papers:
