      This data file contains magnetometer and spacecraft trajectory data in  
      planetocentric (PC) coordinates. The data file is                       
      ASCII and includes an attached header (407 lines, 22223 bytes) and      
      data table. The data are provided at the full word instrument downlink  
      resolution which varies by orbit. The time tag provided is the          
      Universal Time (UT) at the spacecraft when the sample was taken.        
                                                                              
      The PC coordinate system is the standard body-centered cartesian        
      planetocentric coordinate system. It is body-fixed and rotates with     
      the body (Mars) as it spins on its axis. The Z-axis is taken to lie     
      along the body rotation axis and to be positive in the direction of     
      angular momentum. The X-axis is defined to lie in the body's            
      equatorial plane, perpendicular to Z and in the direction of the prime  
      meridian as defined by the IAU. The Y-axis completes the                
      right-handed set."
