                This file contains 48 second averaged from the Voyager 1 magnetometer 
                provided in Inertial Heliographic (IHG) coordinates during the 
                Uranus Encounter and Uranus-Neptune Cruise. 
                These data cover 1986-01-01T15:25:53.121Z - 1986-12-31T18:47:00.743Z.

                These data was extracted from the NSSDC archive for distribution  
                by the PDS. These data were not submitted to the PDS for archive 
                and have not been through the PDS peer review process. These data

                    This product, 1986_VG1MAG_IP.TAB was originally released
                    as part of the safed PDS3 VG1-SW-MAG-4-SUMM-HGCOORDS-48SEC-V1.0 data set. 
                    The metadata have been migrated to PDS4. The data themselves are unchanged.
