 * Latitude, longitude and ellipsoid height are computed from their
   corresponding cartesian coordinates using dimensions for the
   GRS 80 ellipsoid: semi-major axis = 6,378,137.0 meters
                          flattening = 1/298.257222101...


 * WARNING: Mixing of antenna types can lead to errors of up to 10 cm.
   in height unless antenna-phase-center variation and antenna-phase-center
   offset are properly modeled.  See next comment.

 * The coordinates shown on this page were computed using absolute antenna
   calibrations.  CORS coordinates began using absolute antenna calibrations
   beginning with IGS08 and NAD 83 (2011, MA11, PA11).  For additional
   information on the derivation of these positions and velocities and
   antenna calibrations consult:

   monumentation type consult:

 * The position & velocity were revised in Aug 2011.
