Jamie and I have the MC spots centered. We did the normal move the input beam, realign jazz for a while, then when we got close, used the "move MC2 spot" scripts to get the MC2 spot back to ~center.
This was way easier when the measurements were real, and not just noise. Funny that.
The dark blue spot is the farthest from 0 in pitch, and it is 1.04mm. The cyan and yellow we've done a pretty good job of getting them equally far from zero. Since we aren't translating the beam, we can't get better than the point at which the cyan and yellow curves cross.
