Travis said that he had some locklosses because of the DRMI ASC (only BS so far in O3), and since we saw the same thing this afternoon, we tried to work on the DRMI ASC.  

We found that our old ASC loops were fine for INP1, PRC2, and SRC2, and that we can increase the gain of SRC2 so that both pitch and yaw have a gain of 60 (factor of 6 increase for Pit, factor of 3 increase for yaw).  We found that the 45Q signals we had been using for the beamsplitter had almost no response, especially in yaw.  We also found that the AS72 signals we used to use for SRM were not near a zero crossing for a good alignment.  We weren't able to find a good error signal for the beam splitter.  

We have reverted the guardian, but left our new input matrix commented out.  Operators who have trouble over the weekend with DRMI ASC can try running initial alingment.
