FC recovery

Marc, Michael

On Wednesday we started the FC recovery.

First we checked the OpLev spectra and it seemed fine (no extra peaks indicating touching).

The PR references are good meaning that the squeezer alignment were good.

We moved PR picomotors to recover the reference on BS chamber.

We started to move BS picomotors to recover the beam on the 2 targets. But at some point the pitch picomotor stopped moving..

We did ~2000 steps for pitch.

We checked the OpLev spectra again and seemed fine so no touching.
