Hoping to get some good quiet time with H2 SUS ITMY after the chamber has finally been pumped down to a few x 10^-7 Torr, I took a quick glance at the OSEM alignment after noticing that M0 Damping loops were not on. Attached are screen shots of the OSEM alignment speedometers; they show that the Vertical/Roll sensors (M0/R0 LF and RT) have either lost their signal, or the flags are occulting the the LED/PD. M0's LF and RT are showing basically ADC noise and "off the radar," R0's LF and RT are at least on the radar (and should still be usable).
As such, I've left the system in a state where
M0 L, T, P, and Y are damped
R0 L, T, V, R, P, Y are damped
and from my quick glances at BSC 8 ISI and BSC8 HEPI overview screens, I see that
HEPI is OFF
ST1 and ST2 Damping is ON
One can consider this state to be the case starting at

(and should true for at least another hour.)
