      <Description>
   Hourly averages and peaks of calibrated electric field spectrum analyzer data from Voyager 1 PWS instrument
    
   The plasma parameters are obtained by finding the best fit of a convected   
   isotropic Maxwellian distribution to the data. One sigma errors             
   are typically less than 0.5% in the speed and VR, less than 5% for the      
   density and thermal speed, and vary greatly for VT and VN.                  
   Sampling times range from 12 to 192 sec., with sampling generally more      
   frequent early in the mission.
                     
   The velocity components are given in the RTN coordinate system,             
   where R is radially outward, T is in a plane parallel to the solar          
   equatorial plane and positive in the direction of solar rotation,           
   and N completes a right-handed system.
