Yesterday (Tues) morning, we adjusted the alignment into the PMC to minimize the reflected light level with the cavity locked.
We adjusted the two steering mirrors immediately upstream of the PMC.  Neither was locked before, but we locked them this time when we finished.
Maybe this will help with the alignment drifts we have been experiencing.  Min. REFL DC level was 0.375 V locked, 2.3 V unlocked.

We then did a cursory alignment into the reference cavity and saw a significant improvement using the two mirrors downstream
of the PMC (again, neither of which was locked).  Trans. level 2.08 on MEDM screen.
We looked at the FSS OLTF and adjusted the gains to 15/30 dB Fast/Common.  Even with the common gain at the max level of 30 dB,
the UGF is only about 320 kHz.  Phase margin about 50 deg.

We installed the insulation end caps on the reference cavity.  This may provide some passive improvement in the temperature stability.

With JeffB (operator on shift) we adjusted the ISS reference level to 2.00 to account for the increased light level resulting from the PMC
input alignment and locked the ISS loop.  The diffracted light level was about 7.4 W and the loop appeared to be functioning properly.
This reference level will have to be adjusted to keep the diffracted light level in the 6-10 W range if the PMC alignment drifts (reflected
light level increases).  0.01 on the reference level is approximately 1% (maybe 1.3%) on the diffracted light level.

We need:
AA batteries for the computer keyboards and trackpads.
15 ft. SMA/SMA cable for the RFPD to TTFSS servo module cable so we can move the module to the floor (and get this heat source off
of the table).
10 ft. SMA/BNC cable for the ISS AOM to AOM driver cable so we can move the module to the floor and get this heat source off of the
table surface too.
