We have closed 6 low bandwidth loops with DRMI locked with arms off resonance today, based on what we learned from talking to LLO yesterday:

INP1: REFLA9I-REFLB9I -> IM4 PIT and YAW

PRC2: REFLA45I-REFLA9I -> PR2 PIT only (YAW signal seems to have an offset)

SRC1: ASB36I-> SRM pit only, although error signal loks OK for Yaw as well

MICH: ASB 36Q -> BS, PIT and YAW

In the past we had phased AS36 to maximize the BS signal in Q, but we noticed today that the Q signal is contaminated by SRM.  We rephased AS B 36 to minimize the SRM signal in Q, this reduced the SRM pitch motion seen by AS36 B Q by 40 dB.  

We have not attempted to close the AS_C-> SR2 loop, since we are far off center on AS_C.  It seems that we will have to check search for the alignment that minimizes clipping on the Faraday and use picomotors to re-center AS_C,; we already know that we are clipping on AS_C when we are well aligned for the OMC PDs.  (alog 16831 ).  Despite this, it looked like ASB 36 I was a decent signal for SRM in both pitch and Yaw.
