Here are a bunch of PDFs of time series from last night's CARM sweeps.  The y-axes are all calibrated (except for the TRX/TRY, which are just normalized to single arm power, as usual) to real units - meters for the error signals, and Newtons for the control signals.  The y-axes for each plot are the same on all PDFs (ex, the control signal plot in the lower left has the same range for all cases) so that it is easy to compare directly. 

The most striking thing is that while the PRMI is held on REFL33, the MICH control signal saturates as we go through arm resonance.  If the PRMI is held on REFL165, there is no such problem.  I think we're going to have a lot more luck keeping the PRMI on REFL 165.
