J. Kissel I've captured a standard sensing function suite, and was able to get in a full L3 and some on an L2 actuator sweep today. Attached are updates to the sensing function collection of measurements. These thermalized data sets are showing *pretty* consistent results. I'm working on getting more channels from the frames (PSL input power, temperature in the LVEA) to see if I can find other things that can predict the trends I see in f_s^2. One idea I had was that the steps between lock stretches are correlated to whether an initial alignment was run. I think I can conclude that there's no correlatino there. We're also working on backing out how bad things are *during* thermalization, with the data gathered yesterday (LHO aLOG 53951).
