BCS Data: Dynamic Variation

The Equinox data set contains Beam Characterization System (BCS) videos and image sequences which show the variation in beam pointing due to heliostat oscillations induced by wind. It also includes contemporaneous wind speed and direction data collected from a weather station in the vicinity.
