I checked pitch/yaw TF for all mirrors and coil response for all magnets. PR/BS/END are fine.

For INPUT, input oplev spectrum was strange (Fig. 1). Yaw seems fine, but pitch had a huge 50Hz peak. I checked the dark noise and there was no huge 50Hz peak, so the 50Hz peak came from oplev laser source. I power cycled the oplev laser source and then the 50Hz peak disappeared (Fig. 2).

I checked the input pitch/yaw TF. Both of them are smaller than before by a factor of 10, but the shape is fine. I also checked each coil response. They seem fine, but yaw TF is larger than before by a factor of 10 in H2, H4.
