PMC and MC alignment are both shit, although with the WFS on, the MC is pretty good. We're leaving it for now, so that (a) we don't mess up Koji's work, and (b) we can work on the Xarm. Steve is doing Yarm oplev stuff, so we'll do Yarm later.

We pushed on the MC SUS connectors at the back of the rack, and that helped bring MC3 back to where it should be. Then we looked at MC RFPD DC, and adjusted the optics with the WFS off, so that the refl is ~0.56. Then when we turn the WFS on, the alignment doesn't really change, so we have offloaded the WFS.
Now we're measuring the spot positions to check where the MC is. Then we'll align the arms, and align the green to the arms.
