Large-Scale Vector Field Maps at a Common Altitude of 37 km.                  
The spatial resolution of the grid (0.25 x 0.25 degrees) is much              
less than the mean S/C altitude.                                              
                                                                              
The measured parameters consist of the three vector components                
of the lunar crustal magnetic field in East, North, and Radial (ENR)          
coordinates, and the field magnitude at an altitude of 37 km.  The            
units of the field measurements are nanoTeslas (nT). 1 nT = 0.00001           
Gauss.  ENR coordinates are centered at the instantaneous spacecraft          
location with X directed eastward, Y directed northward, and Z directed       
radial to the Moon.                                                           
                                                                              
  File naming convention:  B_aaa-bbbc_ddd.TAB, where:

       longitude for the file;                                                
     c is the letter N, S, E or W, indicating a compass direction             
       (this also tells you whether the aaa and bbb are latitude              
       or longitude; for example, if c is E, then aaa-bbb must                
       be east longitude);                                                    
     ddd indicates which field component is mapped in the file

   File name example:  B_120-180E_RAD.TAB describes the radial
