Jeff, Stefan We did the PR2 M3 pitch L2P decoupling today. Plot 1: transfer functions: - blue: measured L2P TF - green: measured P2P TF - red: L2P/P2P (from measured data) - black: fit (note that we paid more attention to the frequencies below 1Hz, because they matter almost 2 orders of magnitude more (see L2P) - Purple: fitted filter times measured P2P. Plot 2: 3e5cts drive to H1:SUS-PR2_M3_LOCK_L_EXC, first at 0.75Hz, then at 0.95Hz. At both frequecies we get about 1 order of magnitude suppression.
