Today, while waiting for violins in OMC_WHITENING, we noticed the SQZ_ANGLE_ADJUST servo takes the SQZ angle away from nominal, plot attached. Sheila suggests this is becasue the OMC_WHITENING state will have different ADF phase to NLN. I think this was the cause of our bad squeezing in one lock 5th Jan too, plot attached.

SQZ_MANAGER turns SQZ_ANG_ADJUST to ADJUST_SQZ_ANG_ADF in FREQ_DEP_SQZ, I left this the same and  added a state WAIT_SQZ_ANG_ADF in SQZ_ANG_ADJUST to wait for ISC_LOCK to be in state 600 before going to ADJUST_SQZ_ANG_ADF  with notification "Waiting for IFO to get to NLN". New graph attached.
