We were having unstable MC locking so we did some physical alignment touch up. Use MC suspension bias to have good MC alignment. Unlock MC and align DC beams to center on WFS. Re-lock and things are now stable.
Someone had been feeding bad info to Eric about MC alignments; we do not center the MC WFS beams with the MC locked.
However, in any case, today the MC2-TRANS servo was not being good so I turned it off. We need the real matrix measurement to bring it back.
