                This file, PVO_OEFD_24S_1888.TAB, contains wave electric field amplitudes measured
                at four different frequencies by the Pioneer Venus Orbiter Electric
                Field Detector.  The data are averaged over 24 second intervals on 12
                second centers.  Each averaging interval contains both the minimum
                amplitude, average amplitude and peak amplitude for that interval at each 
                of the four frequencies.

                    This product, PVO_OEFD_24S_1888.TAB, was originally released in 1994 
                    as part of the PDS3 PVO-V-OEFD-4--EFIELD-24SEC-V1.0 data set.
                    The metadata have been migrated to PDS4. The data have been converted 
                    to ASCII, but the data values are unchanged.

                        Maximum wave amplitude per root Hertz per 24 
  second interval, measured at 100 Hz.  At a particular frequency the wave    
  electric field amplitude (V/M) is measured over the bandwidth of the filter 
  (30% for OEFD).  The square root of the bandwidth is incorporated in order  
  to compare measurements made with this instrument with other wave           
  measurements, which may have different bandwidths.

                        Minimum wave amplitude per root Hertz per 24 
  second interval, measured at 730 Hz.  At a particular frequency the wave    
  electric field amplitude (V/M) is measured over the bandwidth of the filter 
  (30% for OEFD).  The square root of the bandwidth is incorporated in order  
  to compare measurements made with this instrument with other wave           
  measurements, which may have different bandwidths.

                        Maximum wave amplitude per root Hertz per 24
