These are some reference data from a long lock on the weekend.  There are 3 hours of continuous lock between 14:00 and 17:00 UTC (2012-07-08).  The long locks show a full tidal cycle; 1450 counts on the BOSEMS sensors ~ 580um ~ 50k counts of drive at the top mass.  It also shows very little residual L2Y coupling, and a little L2P (which I later tried to remove with an L2P coefficient of 3e-4).
