Note:
    The differential coordinates are from the RCM4 GPS monument to the VLBI 7219 reference 
    point and the RCM2 GPS monument. These numbers are derived from a GPS survey conducted
    in August, 1993 with three Rogue receivers. The repeatabilities are within 2mm.

    The antenna vertical height (from the monument to the bottom of the chokering) at
    RCM2 is 0.094m.

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).
