                This file contains 1 hour averaged from the Voyager 2 magnetometer 
                Heliographic (HG) coordinates during cruise. The data begin in 1990 
                and go through the end of 2004.
                
                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.

                    This product, VG2MAG_1HR_1990_2004.TAB, was originally released 
                    as part of the PDS3 VG2-SW-MAG-4-SUMM-HGCOORDS-1HR-V1.0 data set. 
                    The metadata have been migrated to PDS4. The data themselves are unchanged.
