Time series from HVER

HVER

Figure 9: The horizontal and vertical motion of HVER relative to REYK as a function of time, since the start of the measurements there. Each dot represents a 24 hour solution. The motion in east, north and up directions is defined to be positive, and is given in units of millimeters. The error bars indicate 1$\sigma $ confidence limits. The thick black lines show the best fit (weighted least squares) velocities calculated for each component of motion, after outliers have been deleted. The antenna radome was first installed on day 221, taken off on day 309 and installed again on day 328 (shown with dotted vertical black lines). The radome was re-oriented on day 235. We do not estimate the vertical velocity because the time series are too short between changes in the radome.
