[TVo, Jenne, Sheila]

TVo and I were struggling to lock the IMC this morning, so we went to go look in the LVEA at the RFPD signals.  We weren't seeing anything at all, despite the beam being well centered on IMC Refl PD.  Sheila helped us flip the whitening switches and then power cycle the PD interface board (slot 11 on the ISC R1 rack).  After the power cycle, we were seeing PDH-like signals at the output of the demod board.  So, we're not happy that we don't know why that box needed power cycling, but things seem okay for now, so we're moving forward.

After some more alignment tweaking (and a long break for the PSL recovery after it tripped), TVo and I were able to get the IMC locked.  We're in process of trying to get the WFS loops on, and get the aligment to a good place - we hope to finish this tomorrow.
