An Isolationist Data Miner's Dream...
I've set up the ITMY and ETMY chambers in (what I *think* is) their current best-performance state, such that we can get a nice long quiet stretch of data over the weekend. I say *think* because I never nailed down Fabrice enough to tell me the exact blend configuration of the ISIs that was best for the cavity. Also unfortunately, I didn't catch the ISC team in time to request a lock of the cavity, and I don't know how to do it myself :- (which naturally means there's no ISC control going to either chambers).

ANYWAYS, Here's the setup, as of Jul 28 2012 02:00 UTC (7:15p PT, 1027476016):

        - (No sensor correction or feed-forward)
    - ETMY
        - ISO Loops ON; X, Y, Z, RX, RY, RZ, HP, VP

AND, the Optical lever beams are on the QPDs for both test masses. 

I've made copies of each of the above mentioned systems Foton Filter files, and stuck them in the userapps repository under,

and committed to revision 2718.
