PSL 10-Day Trends

FAMIS 31099

Jason's FSS alignment in the enclosure last week (alog86315) is clearly seen on several trends. PMC transmitted power has also been getting lower seemingly due to the average ISS diffracted power making a few steps up over the past week; not sure if I have an explanation at this point for that. Next time the IFO is unlocked I can double-check the diffracted power and make sure it's staying at the desired 4.0%; right now it's a little high at 4.2%.
