                This file contains 1 hour averaged solar wind data from the Voyager 2 
                magnetometer provided in Heliographic (HG) coordinates during the 
                interplanetary cruise. The data begin in 1977 and go through the end 
                of 1989.
                
                These data have been extracted from the NSSDC archive for distribution  
                by the PDS along with other Voyager solar wind data sets.  These data   
                were not submitted to the PDS for archive and have not been through     
                the PDS peer review process.  These data are provided by the PDS for    
                the convenience of PDS users.  Please exercise caution when using these 
                data.
