This data set consists of Voyager 1 Saturn encounter ephemeris data in       
Heliographic coordinates covering the period 1980-11-10T00:00:34.923 to      
1980-11-20T23:58:59.065. Two versions, both covering the same time period,   
but containing slightly different data, are provided. One version was        
generated by the Voyager MAG team from Voyager 1 SEDR, the other by the      
PDS/PPI node using the VG1_SAT.TSP and PCK00006.TPC SPICE kernels.           
                                                                             
Due to inaccuracies in Voyager SEDR, as well as changes in the values of     
some key parameters (e.g. Saturn radius) the timing is improved for the      
SPICE generated data. However, since much of the original analysis was based 
upon the SEDR generated ephemeris, this data has been included as well.
