The guardian is currently set up to go to 40W requested (actualkly 37W).. With the interferometer sitting at this power level for ~1h I picked a possible SRC input matrix: Both A36I and B36I have signal, but different offsets. The combination below brings us to a good sideband buildup:

for SRC1_P:
AS_A_RF36_I : -0.5
AS_B_RF36_I : +1.0

for SRC1_Y:
AS_A_RF36_I : -1.5
AS_B_RF36_I : +0.34

Attached are snapshots of the input matrices at 37W
