These are some trends that Tony and I made over the weekend that would be useful to have in the log.

The first trend shows a couple of months, our PRG has been degrading for about 30 days.  This looks to be correlated with the PR3 optical lever, but that optical lever (along with many other alignment and vertical sensors) correlates with outdoor temperature.  The COMM beatnote depends on the PR3 angle, this was re-adjusted on the table 74065 a month ago, but also looks to have been dropping over the last few weeks.  The second screenshot shows that move of PR3 (and PR2) that Corey and I did on Friday night improved the PRG back from 40 to 48 (at the max of the thermal transient), improved the COMM beatnote slightly, and brought the PR3 optical lever partially back to where it was a few months ago. 

The last attachment shows some sensors related to PR3.  The IPS and CPS say that HAM2 hasn't moved in yaw.  The osems and optical levers do not agree about what has hapened with PR3, the optical lever says that we have had a drift in the positive yaw direction, and that we partially reversed that on Friday night.  The top mass damping says that we had a negative yaw drift, and that our move Friday night went further in the direction of the drift.

The last attachment shows some similar sensors for SR3, which doesn't have as large of a drift.
