    measurements ordered by time, including DSN station IDs and               
    estimated measurement error, from Viking Lander 1, which were             
    used in conjunction with data from Mars Pathfinder to solve for           
    Mars rotation parameters.                                                 
    Note that DSS station 61, was raised 10 feet on 9-AUG-1979,

    value for data before that time.
