                  BROWSE/PROJECT Directory Contents                           
                                                                              
The PROJECT subdirectory of the BROWSE directory contains a system of         
images and related files that provides a simple method for browsing           
through the NEAR MAG archive.  The images are in JPEG format.  The            
system is designed to be viewable by many WWW browsers.                       
                                                                              
The PROJECT directory has a structure identical to the DATA directory         
on this CD.  Each subdirectory contains plots of NEAR MAG data in NEAR        
Sun Orbital (NSO) and Eros Body Fixed (EBF) coordinate systems.  NEAR         
Sun Orbital (NSO) coordinates are Cartesian coordinates defined with          
respect to the NEAR-Sun line and the orbit plane of Eros.  The X-axis         
points from NEAR to the Sun, the Z direction is given by the Eros             
velocity vector crossed into X, northward normal to the Eros orbital          
plane, and Y completes the right-handed set.  Eros Body Fixed (EBF)           
coordinate system has its Z-axis along the Eros spin axis, the X-axis is      
in the Eros equatorial plane, and lies in the direction of the prime          
meridian. The Y-axis completes the right-handed set.  Data used for the       
plots are the same as those provided in ASCII format in this data set.        
                                                                              
Spacecraft position relative to Sun is indicated at the top by radial         
distance and solar ecliptic longitude and latitude.                           
                                                                              
NEAR position relative to Eros is shown in two ways.  In the top              
panel, NEAR location relative to Eros is shown by Clock Angle and             
Excursion Angle. In the bottom two panels, NEAR location relative to          
Eros is indicated by longitude, latitude, and distance, defined in EBF        
coordinates.                                                                  
                                                                              
The PROJECT directory also contains the file MANIFEST.TAB, which              
contains a list of files that make up the set of browseable files             
located in PROJECT.  Files named INDEX.HTM under PROJECT are parts            
of this set, and the file INDEX.LBL is the PDS label file for                 
INDEX.HTM.                                                                    
                                                                              
The system of images in PROJECT was provided by the NEAR instrument           
team to PDS.  Other browse products, produced from the data by PDS,           
can be found in other subdirectories of the BROWSE directory.
