Just to compare what was posted at LLO yesterday https://alog.ligo-la.caltech.edu/aLOG/index.php?callRep=12702. I ran 128k 3Hz sinewave to each quadrant with -125k bias on the DC and looked at the responses. The good news is it actually responds. The bad new it trying to make it respond to sensible signals like a pitch or a yaw does not yield much in a way a results. I am sure Keita will have more to say. But attached are our results of a 3Hz injection
