This directory contains the 48 second edited browse data from the Radio       
Astronomy instrument on Voyager 2.  These data were collected from the        
Jupiter encounter period of 1979-04-25 to 1979-08-04.  Data are provided      
for 70 instrument channels, each 1 kHz wide and separated by 19.2 kHz,        
covering the range from 1.2 kHz to 1326 kHz.                                  
                                                                              
The data are stored as an IEEE binary file (.DAT), accompanied by a PDS       
label file (.LBL) which describes the properties of the data files.
