For those of you computing away in the late evening, or early am:
Vacuum status: started pumping around 9:45 after having installed
the 3 flanges we removed. Had both DPs pumping on the vessel
just under 2 hours later. Presumably physics level vacuum, but
I can't tell as I don't have the ion gauge turned on, and should
not access the hall until 7am, at which time the vessel will have
been under vacuum, mechanically speaking, for 8 hours.
