This morning I adjusted the alignment into the reference cavity.  Mostly vertical adjustments on
the periscope were done.  When I started the reference cavity transmission was ~0.6V, afterwards
~3.56V.

    Measured the open loop transfer function.  Originally with the common gain slider at 16 dB.
After the measurement I changed this to 18 dB to sit at the peak of phase bump.  As I was measuring
the transfer function at 18 dB, a glitch of some sort occurred which resulted in a loss of 2 dB
in the unity gain frequency and not sitting on the peak of the phase bubble.  Coincident with the
glitch I noticed that the Pockels cell monitor saturated, perhaps caused by the input modecleaner
trying to acquire?

    The difference in the common gain is not much.  It might be better to return to 16 dB if 18 dB
is problematic for some reason.
