[Paco]

Installed AS1 in vacuum, near the center of the table, and installed the OSEMs. All OSEMS are "balanced" nominally, i.e. their shadow is at the halfway point optimum, but fine tuning is required, which I will attempt tomorrow after restoring the AS1 suspension screen settings. Today, I tried damping the SIDE DOF, but didn't succeed, although there was definitely some oscillating behaviour with high (> 5) gains on the damping, so I believe this is a matter of patience. For now, all OSEMs are looking ok, the SOS is in place, and hopefully it will soon be damped.
