velocity in mm/yr. Sn = standard deviation of North component of velocity in mm/yr. Ve = East component of velocity in mm/yr. Se = standard deviation of East component of velocity in mm/yr. NEcorr = North-East velocity correlation. a = semimajor axis of 1-sigma error ellipse in mm/yr. b = semiminor axis of 1-sigma error ellipse in mm/yr. C = Azimuth of semimajor axis of error ellipse. Vel. = magnitude of velocity vector in mm/yr. Az = Azimuth of velocity vector. Velocities labeled 'Savage' are from Savage et al. (2000, Journal of Geophysical Research). See http://quake.wr.usgs.gov:80/QUAKES/geodetic/gps/CapeBlanco/ Those with an asterisk were not used in the inversion - we used our calculated velocity instead. All velocities are relative to North America. See Savage et al. for how theirs are determined. Ours are rotated into the NA frame using the NA-ITRF96 pole of DeMets and Dixon (1999 Geophysical Research Letters).
