     * Moving peaks exist, but amplitudes are not so high and frequency is far from controls. -> accept
     * 2nd and 3rd graph shows it can be removed when evacuated. -> accept, we should check it after the pump down.
  * A10: Transfer Function -> accept
   * Transsfer function : https://klog.icrr.u-tokyo.ac.jp/osl/?r=29138
    * F0 is close to the edge, so the gain is high. -> accept
    * F1 is within the range enough, we have no explanation for why the gain is so high. The reason for the dip of 8Hz depends on coupling, the earthquake might change the coupling. 1.6Hz peak showed in the new data, but we do not know why. However, no control is applied, so -> accept
