IP1 and IP2 gate valves opened fully this morning
IP1 and IP2 were found to be at course vacuum (~1-15 torr) yesterday after aLIGO removal, years of storage and subsequent re-installation.  We had "roughed" them out yesterday, started their HV but had left them only partially open to the vertex volume overnight.
