Subject: Spot centered on BS, ETMY, ETMX 

[Unni, Manasa, Jenne]

It turned out that the beam was a teeny bit high in the corner, so we touched PZT1 and PZT2 knobs to translate the beam down a bit.

Now the beam is centered on the BS (using the 45 degree non-iris target), centered on ETMY (using Steve's latest target, which worked perfectly), and then BS was aligned a tiny bit (really, it didn't need much) to get the beam centered on ETMX.

After dinner I'll align ITMX and ITMY such that their beams retroreflect and I get MICH fringes.  I'll also align SRM and PRM to retroreflect.  Check no clipping on AS path, get REFL path out, center IPPOS and IPANG, check POX, POY and POP.  Then, I think we might be almost done.
