This document was created during the NEAR NLR migration from PDS3 to PDS4 and contains all the information needed for the entire NEAR NLR raw data collection. This document was created from the combined contents of the PDS3 dataset.cat files for all phases of the NEAR NLR mission.

      This document provides an overview of this volume of the Near Earth       
   Asteroid Rendezvous (NEAR) Uncalibrated Data Set, including a summary      
   of the volume contents.                                                    
                                                                              
   The NEAR Science Data Center (SDC) archives NEAR uncalibrated science      
   data to the Small Bodies Node (SBN) of the  Planetary Data System (PDS),   
   as specified in the NEAR Project Archive Generation, Validation and        
   Transfer Plan (February 1998).                                             
                                                             
                                                                                                               
  File Formats                                                                  
   ============                                                                  
                                                                              
   The data files are presented in both the PDS and FITS form.  In the        
   latter case, a FITS to PDS translator program (F2P) has been used to       
   create the detached PDS labels for each corresponding FITS file.  All      
   document files and most labels contain an 80-byte fixed length record,     
   with a carriage return (ASCII 13) and line feed (ASCII 10) as the 79th     
   and 80th byte respectively.  This allows the files to be read by           
   MS-DOS/Windows, Unix, and VMS operating systems.  All the tabular files    
   in the INDEX and DOCUMENT directory are formatted according to PDS         
   standards.  It should be noted that the index tables are formatted so      
   that they may be read directly into many database management systems.      
   All fields are separated by commas, and character fields are inclosed in   
   double quotes (").                                                                                   
                                                                              
                                                                              
    Parameters

      The definitions for the image parameters and other keywords are         
      given in the file NLRDEFINITIONS.TXT contained in the nlr_column_definitions.txt document in the                  
      document/data_raw subdirectory.

      The data are in the form of FITS files with attached FITS headers       
      and detached PDS labels. Files contain all data for one day.
