Time series from VOGS

Figure 8: The horizontal and vertical motion of VOGS 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 confidence limits. The thick black lines show the best fit (weighted least squares) velocities calculated for each component of motion, after outliers have been removed. The antenna radome was installed on day 328 (shown with dotted vertical black lines) causing an estimated 21 mm vertical offset.
