This morning, after my failed attempt to engage the new LLO-imported filters on the SR3 damping loops, Evan managed to be successful. Attached is spectra of the SR3 OPLEV PIT and YAW signals comparing the original state of the SR3 (LHO filters and gains, OL damping enabled) with engaging the filters. Note, I increased the gain to compliment the LLO ones a few hours after we switched the filters and added new spectra. It does not apear that the new loop filtering and gain are helping, but instead hindering. Hmm... I've since dropped the gains back to the original LHO values, and leave it to the commissioners to flip back the filters if they see fit.
