 NE0733.The horizontal coordinates were scaled from a topographic map and have
 NE0733.an estimated accuracy of +/- 6 seconds.
 NE0733
 NE0733.The orthometric height was determined by differential leveling
 NE0733.and adjusted by the National Geodetic Survey in June 1991.
 NE0733
 NE0733.The geoid height was determined by GEOID99.
 NE0733
 NE0733.The dynamic height is computed by dividing the NAVD 88
 NE0733.geopotential number by the normal gravity value computed on the
 NE0733.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 NE0733.degrees latitude (g = 980.6199 gals.).
 NE0733
 NE0733.The modeled gravity was interpolated from observed gravity values.
