Settings for Successful Alignment into HAM6
J. Kissel for K. Kawabe, B. Weaver Successful alignment work into HAM6 (I'm sure an aLOG is pending), but just to get it in ASAP before the next computer crash: here's the collection of alignment sliders and how things looked on the QPDs / DC components of the WFS at the AS PORT: the on-board OMC QPDs (H1:ASC-OMC_[A or B]_[PIT or YAW]_OUT16), indicating the beam is going into the OMC, and then the on-table QPDs that get light transmitted through various OMs -- the DC components of the AS_WFS_[A or B] (often colloquially referred to as QPDs) and the *actual* QPD, AS_C. I also attach a trend of the channels.

** Here, I invoke the colloquialism where I refer to the DC components of the WFS channels as "QPDs."
