Here is the table of our campaign GPS sites. This is table 1 (data for figure 1) of the online version of the science paper. These are the velocities with the NA plate removed (residuals). Position and velocity (with corresponding errors) are shown for each of 23 campaign sites. Sigma1 and Sigma2 are the major and minor axis of error in velocity estimates. Sigma1 is rotated by the azimuth (reported in degrees clockwise from north). SITE Lat. Long. Nvel. Evel. Sig1 Sig2 Azm.
