all velocities in mm/yr. 

(1) GPS_vectors_after_rotation.dat

These are the observations that have been rotated into a model Eurasia frame
of reference.  The rotation vectors, plus full covariance matrices, applied to 
each study to rotate into a best fit model Eurasia frame of reference are 
supplied in a table (GPS_rotation_vectors.ps).


(2) velocity_vectors_at_GPS.dat

These are the velocities predicted by the model at the GPS sites.  These are in
a model Eurasian frame of reference. The model velocity field has been fitted
to the GPS vectors that have been rotated into the optimal frame of reference.
These GPS vectors are presented in GPS_vectors_after_rotation.dat.
