It seems like Detchar must already be aware of this, but we are having huge glitches durring this lock long lock stretch, which show up in auxiallary degrees of freedom. We were wondering if anyone has checked for things like DAC crossings, or saturations.
We're currently checking for DAC glitches, hopefully have an answer shortly
I checked for correlations of the glitches with the ASC error signals residual motion around zero, and with suspension witness sensors and optical levers. I couldn't find anything convincing.
