 KT1966.The horizontal coordinates were established by classical geodetic methods
 KT1966.and adjusted by the National Geodetic Survey in March 1994.
 KT1966.The horizontal coordinates are valid at the epoch date displayed above.
 KT1966.The epoch date for horizontal control is a decimal equivalence
 KT1966.of Year/Month/Day.
 KT1966
 KT1966
 KT1966.The Laplace correction was computed from DEFLEC99 derived deflections.
 KT1966
 KT1966.The geoid height was determined by GEOID99.
