 DX4639.The horizontal coordinates were established by classical geodetic methods
 DX4639.and adjusted by the National Geodetic Survey in June 1996.
 DX4639.The horizontal coordinates are valid at the epoch date displayed above.
 DX4639.The epoch date for horizontal control is a decimal equivalence
 DX4639.of Year/Month/Day.

 DX4639.The Laplace correction was computed from DEFLEC99 derived deflections.
 DX4639
 DX4639.The geoid height was determined by GEOID03.
