* ETMX: *Hasegawa * Damping for yaw woks somehow and RMS is ~0.2urad. * A very high Q peak was found on pitch and it takes several hours to be calm. This high Q seems to be Sphere parts. * ETMY: :Miyamoto, Shishido * No progress for damping. * ETMY: *Okutomi * ETMY TF was measured. Not only 2 but all F1, F2, F3 seem to be locked. Moving FR may fix the lock. |
