 BG0984.The horizontal coordinates were scaled from a topographic map and have
 BG0984.an estimated accuracy of +/- 6 seconds.
 BG0984
 BG0984.The orthometric height was determined by differential leveling
 BG0984.and adjusted by the National Geodetic Survey in June 1991.
 BG0984
 BG0984.The geoid height was determined by GEOID99.
 BG0984
 BG0984.The dynamic height is computed by dividing the NAVD 88
 BG0984.geopotential number by the normal gravity value computed on the
 BG0984.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 BG0984.degrees latitude (g = 980.6199 gals.).
 BG0984
 BG0984.The modeled gravity was interpolated from observed gravity values.
