I measured the TFs of the MCe suspension after Oplev recovery. The pitch mode TFs differed from the reference, but they are similar to the health check results in 2024. We will check the suspension visually.
I measured the TFs of the MCe suspension after removing the clean bag. The coupling to the yaw mode was large (Fig. 1-4). The resonant frequency of the pitch mode was a little lower than the reference (Fig. 6). The behavior of the suspension looks healthy.
I measured the TFs of the MCe suspension after connecting the bellows. The length-to-yaw TF was consistent with the reference (Fig. 5). Compared with the TFs before connecting the bellows, the pitch-to-yaw coupling became larger than the pitch-to-length coupling (Fig. 6). The behavior of the suspension looks healthy.
