    - 70 Hz glitch was not real glitch. When we apply the hight pass filter with 10Hz or use DISPLACEMENT channel, the glitch disappeared.
    - (YamaT) In the end, should we use which channel? h(t) channel with high pass filter or DISPLACEMENT channel?
    - (Yuzu) h(t) channel will be straightforward.
    - (YamaT) If the analysis method is affected by the difference of waveforms, we will obtain the different results, such as SNR. Hveto result depends on magnitude of SNR (by threshold).
