Table 1 Differences in relative vertical deformations of 92110 and 960627 with respect to 06S061 between GPS solutions and measurements by the subsidence meter or leveling. Note that GPS solutions are averaged with a moving window of 10 days. The deviations about the mean in the GPS-derived vertical displacements of 960627 relative to 92110 are also given for comparison.
