Time series from SOHO


Figure 12: The horizontal and vertical motion of SOHO 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 removed. The antenna radome was installed on day 309 (shown with dotted vertical black lines). The tribrack was replaced on day 311. Note that the time scale is different from previous figures.
