Now that we have returned to NLN with 50W, I have made (quick and uncalibrated) comparison plots showing the ASC REFL A and B WFS spectra in pitch and yaw. These plots show success in supressing the 6 Hz peak, and as Jeff mentions in this alog, there are now some high frequency (>30 Hz) peaks present. These spectra were measured at the same guardian state (NLN) and the same input power (50W). Pre-vent is June 4th lock, post-vent is at the time of this alog.
