We've whacked on the HEPI piers and surround floor some more today. We think we finally have a good combination of hit locations, hit strengths, and accelerometer locations that we're measuring the real flagpole motion of the pier at 8 [Hz]. Lots of plots, data, and analysis to come (as we know it's torturous to get data off the B&K system). Glancing at the rotation sensor signal, we found it had rung up to +/- 500 [nrad] during our activity and a visit by Robert, so we did the gravity dance a little bit, such that it now is moving +/- 250 -- Krishna is much better than us at this. We've left the end station as of 2014-08-17 8:00p PDT, or 2014-08-17 03:00 UTC.
