 EF0976.The horizontal coordinates were scaled from a topographic map and have
 EF0976.an estimated accuracy of +/- 6 seconds.
 EF0976
 EF0976.The orthometric height was determined by differential leveling
 EF0976.and adjusted by the National Geodetic Survey in June 1991.
 EF0976
 EF0976.The geoid height was determined by GEOID99.
 EF0976
 EF0976.The dynamic height is computed by dividing the NAVD 88
 EF0976.geopotential number by the normal gravity value computed on the
 EF0976.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 EF0976.degrees latitude (g = 980.6199 gals.).
 EF0976
 EF0976.The modeled gravity was interpolated from observed gravity values.
