 LT0703.The horizontal coordinates were established by classical geodetic methods
 LT0703.and adjusted by the National Geodetic Survey in March 1994.
 LT0703.The horizontal coordinates are valid at the epoch date displayed above.
 LT0703.The epoch date for horizontal control is a decimal equivalence
 LT0703.of Year/Month/Day.
