Sheila, Camilla

The IFO was just relocking at the start of commissioning time today, so we set the ADF back on and the sqz angle servo on.  This worked fine, with the phase shifter staying well within it's range (it stayed between 180 and 130 degrees, it's range is 0 -270 degrees). 

In the attached screenshot the vertical cursors are both at 25 minutes into the lock.  You can see that the SQZ BLRMS and the range behave differently with the servo on, but in both cases they start with a low range and move up slowly.  We think that the set point of the squeezing angle servo wasn't set ideally for this time.

In the second screenshot you can see that I changed the SRCL offset and the servo responded to it, taking about 3 minutes to settle.
