            <Description>This data set contains power of electromagnetic wave components from 
narrow band (10%) filters at 140, 450, 800, 4500, and 15000 Hz.  For 
any given time segment the power for any one of five predefined pairs 
of the five measurable field components (EZ, EH, BZ, BX, BX45) were 
measured and are included. The components of electromagnetic field 
are named by their direction in the satellite frame.
Spacecraft position in geographic and 
magnetic coordinates are also included, along with time and an 
indication of which pair of components were measured.
  Each data file corresponds to one memory readout, and 
typically consists of a few continuous-data segments.  The first 
several records in each file constitute a header giving the time spans 
of the segments, the time resolution, and other common information.  
The data records are in ASCII.</Description>
