Yesterday we realized the tilt oplev signal was giving a unsuitble values. Namely, 98 (in normalized displacement units) in the QPD vertical direction (called PIT in the medm screen) and 69 in the horizontal direction (called YAW in the medm screen). Suitable values are within [-50,50], which is the linear range. The consequence is that the pitch DC control feedback signal drifts. This morning the payload tripped.
The aim is to move the QPD tomorrow morning, which is Friday.
