Today we used the HAM7 in-vac picomotors on D:M1 and D:M2 to re-center the squeeze beam on the in-vacum RLF QPDs, which are used for both filter cavity ASC + LSC. Before pico-ing, the FC retro-reflected beam was quite mis-centered on RLF_QPD_B, and we had to walk the beam considerably in pitch to re-center on the QPD's, see the before vs after QPD centerings. Now that we are servo-ing the beam going to the filter cavity (with FC beam spot control LHO:69374), hopefully now we will have a stable FC injection axis, and a stable retro-path through HAM7.
