FSS and PMC locked together
Tahara, Nakano, Stefan

- We installed a new cable for the FSS EOM path and re-phased the signal with cables.
- Found a FSS fringe and locked the FSS. Tweaked up the alignment for the RevCav trans PD.
- Installed a temporary analog camera on RevCav REFL (this diabled the REFL DC PD for now).
- There is no higher order mode visible on the camera when the FSS is locked. However the reflected 00-mode is rather big, suggesting this cavity is not very close to critically coupled.
- Pulled the PMC daughter board for a whitening modification on the MIXER and FAST MON channels.
