We did a quick test of squeezing for different SRCL offsets.  

We found that the best squeezing is at a slightly different phase than we had been using, the total of OMC3 and HD3 (both of these are really used as 6MHz demods in the CLF chain) should be 63.66 degrees.  The squeezing level isn't very sensitive to getting the phase exactly right, since we have a low level of squeezing.  We cannot adjust the phase to better than ~5 degrees.

We next tried introducing an offset in the SRC cavity length, the improvement we saw was due to an improvement in the reference shot noise without squeezing, not due to squeezing.  We did this with Jenne's SRC ASC offsets on 47585, and the level of squeezing we started with was a little bit worse than normal.  Dan is now removing the SRC ASC offsets to see what happens. 

There is a reference time for checking the cross corelation from 22:02-22:20 UTC on March 17th.
