As we begin to investigate transient issues with the Beam Splitter where its sensors are reporting intermittent glitching that is spoiling DRMI locking, the optical lever damping loops are always an open question for me. 

Here's the impulse response of the filters, shown both as a normal time-series, which shows that most of the action happens within the first 0.2 seconds. I also show a semilogx plot of the time series to show the early magnitude of the response.

Finally, I attach a screenshot of which filters are on.
