Data Set Description:

        PIONEER MAGNETOMETER DATA  (JUPITER CLOSE ENCOUNTERS)                                                                                                                                                                                   
                                                                                                           
The data are in JG coordinates, defined as follows:  the X axis is 
in the direction of G, the equatorial vector lying in the System 
III Prime Meridian, 1957.0;  the Z axis is in the direction of J, 
the spin axis of Jupiter; and the Y axis is parallel to Jupiter's 
equatorial plane and completes a right-handed orthogonal system.                                                                         
                                                                                
Each record is 80 bytes long, and contains the following data in 
the format (F7.4, 6F12.4):                                                   
                                                                                
      DTM     Ground received time in days (3.0 = Dec. 3, 00:00).               
              (Year = 1973 for Pioneer 10; 1974 for Pioneer 11.)                
                                                                                
      RR      Distance of Pioneer from Jupiter, in Jupiter radii.               
                                                                                
      RLTJG   Latitude of Pioneer in Jupiter-centered JG system.                
                                                                                
      RLNJG   Longitude of Pioneer in Jupiter-centered JG system.               
                                                                                
      BXJG    One-minute average of x-component of field in JG.                 
                                                                                
      BYJG    One-minute average of y-component of field in JG.                 
                                                                                
      BZJG    One-minute average of z-component of filed in JG.                 

Angles are measured in degrees; fields in gammas.
