[Takahashi, Mitsuhashi]

We measured the spectra of the suspended breadboards again.

PR2: The peak due to the pendulum mode was observed at 0.43Hz, which is consistent with the last measurement. The microseismic was smaller today, so the peak amplitude was smaller than the last one.

SR2: The SNR of the measurement was not good. The peak at 0.39Hz was larger than the peak at 0.33Hz a little, but it's not clear.
