SQZ_ANGLE_ADJUST servo turned off March 25th

Naoki turned off the SQZ_ANGLE_ADJUST servo on March 25th, new nominal is DOWN. We had turned it on in 76556.

It appears that the bucket squeezing (yellow BRLMS that effects range most) is more stable without the servo, with the cost that but 700  to 1750Hz squeezing is less stable (blue and green), plot attached. In the two locks last night all BLRMs seem to take longer to thermalize, probably caused by the IFO being unlocked for longer and cooling down between locks.
