Back at the fight, we were able to get to ENGAGE_DC_VIOLINS for my first lock stretch this morning. Given the messages about the oscillation being seen in MICH, I had had the MICH P ASC gain (alone) reduced from -0.25 to -0.2. From trends courtesy of Niko, the DRMI power builds are essentially no different than before. Violin modes are "not unreasonable." ISS 2nd loop has also been checked for problems, and been cleared. Regardless, a power increase even from 2W to 3W (via adjusting the LASER_PWR guardian alone) triggers the 0.55 Hz QUAD Pitch resonance to ring up the ASC almost instantly. See attached, in which the power-up is at ~-120 sec.
