Started roughing down vertex at 11:17 am local time. Pump curve attached. Someone from vacuum will stay late to babysit the system and then we'll valve out and resume pumping tomorrow morning.

IP1 valve leaks, so we connected a turbo cart to the IP. Pressure looks to be something lower than e-3 torr, so we'll valve that volume back in after we're on the main turbo (with IP powered OFF). Other three IPs look ok (no valve leaks). 

BSC3 & HAM4 door annuli are still on turbo carts.
