Time series of motion at CGPS station HLID relative to REYK

The motion of HLID as a function of time, assuming REYK is stationary, in millimeters. Displacements in east, north and vertical directions are defined as positive. Outliers have not been removed. Please note these are not final results and are subject to change.
An antenna radome was installed on day 235 (vertical dashed line). Large displacements in the north and east components between days 341 (vertical solid line) and 450 is due to snow accumulation on top of the antenna. HLID has been running in semi-continuous mode since March 15, 2000.
