Leaving BSC-ISIs with ST1 ON, and ST2 OFF
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.
