J. Kissel As of 2014-03-10 03:00 UTC (08:00p PT), I've left the functional BSC-ISIs in the following state: ITMY BS ITMX ETMX Iso Blend | Iso Blend | Iso Blend | Iso Blend | HPI Lvl 1 "Pos" | Lvl 1 "Pos" | Lvl 1 "Pos" | Lvl 1 "Pos" | ST1 Lvl 3 "TCrappy" | Lvl 2* "TCrappy" | Lvl 3 "TCrappy" | Lvl 3 "TCrappy" | ST2 OFF | OFF | OFF | OFF I left ST2 OFF, because I want to get a measure for the differences between chamber performance is as related to the differing input motion at low frequency. Unfortunately, the ISI BS's level 3 controller appears to be unstable, so I had to stick with Level 2, but this shouldn't matter for the regions I'm looking to study. I've also made sure all optical levers are aligned.
