Jeff K, Sheila, Jenne,

Today we measured the cross correlation without squeezing, and squeezing at various squeezing angles, as well as the DARM sensing function at 2 differest SRCL offsets.  We wanted to do this before we move the spot positions tomorow, because we have seen that the cavity pole can increase as we change the spot positions and because we have seen that the sensing function can be fit with a SRCL offset at these "August" spot positions, while at the July positions there is a more complicated angular cross coupling involved.  We plan to repeat this set of measurements Wed, after the spot position move. 

We lost lock when we attempted to use a SRCL offset of 200, which had been OK in the past (50591).

While relocking we ran into 3 problems:

• MICH BRIGHT: TJ +Jeff B started an initial alignment but there were problems with MICH BRIGHT.  Jenne and I started to diagnose it and believe that it unlocks with the dither lines are turned on, but decided to just aling by hand and possibly work on MICH BRIGHT durring tomorow's maintence window. 
• TR CARM problem after initial alignment: It seems like after each time that we do inital alignment, we loose lock in the TR CARM steps somewhere.  This is probbly a problem with DOWN not being run somewhere.
• Spot position move:  We lost lock after ADS came on while it was moving the spots.  It looked like the SRC2 ASC error signals weren't being held at 0, so the next lock we engaged the boosts 0:0.05 for SRC2 P+Y.  This seemed to work so we have put it in the guardian.

After relocking we got the measurements at a SRCL offset of 100.  I will post the squeezing data soon, and Jeff K is writting an alog about the sensing function measurements now.
