After the height adjustment in the morning, we found the yaw motion of the filter chain at 45mHz became large. It might be due to decreased damping force in the F1 damper when the F0 setpoint was changed last time. I changed the setpoint for the F0 GAS back to the original (4362) and the F2 GAS from -1428 to -1568 so that the NM V Oplev can be zero. The F0 and F2 GASs were offloaded with the FRs.
