We turned off the WFS servos, and looked at the MC REFL DC, and saw that it was still good, so we said that since the MC spots are pretty good, that we'll keep this alignment for now.
Rana put the beam back on the center of the IOO QPDs on the PSL table.
We switched a steering mirror in the WFS path that was the wrong handed-ness to be the correct handed-ness, then put the beam on the centers of the WFS. We turned on the WFS, and everything seems good.
There were no major drifts in the WFS error signals while we were gone for dinner, so the MC seems okay for now.
