Note: The dX, dY, and dZ are from RCM4 to VLBI 7219 and are derived from a
      4-day (24-hour session per day) GPS survey conducted in August, 1993.
      The repeatabilities of the three components are 1.0, 2.3, and 1.5 mm.


Differential coordinates from the GPS monument to the reference and 
other monuments. The components are parallel to the XYZ-axes of the 
global geocentric reference system ITRF (WGS-84).

"Accuracy" is estimated accuracy of local survey (millimeters).
