We are checking the Gaussianity of the strain data.

We used the data of the silent run on 04/06, reported by Yokozawa-san.

Fig 1 ~ 5: the results by using our tool

• two red bands can be seen, which means the Gaussianity was bad at that time.
  • we don't know the reason

We also checked “Rayleigh statistic” and "spectrogram" on the summary page.

• confirmed that similar behavior appeared in "Rayleigh statistic" (Fig 6,7)
• however, in "spectrogram", we could not find anything.(Fig 8,9)

Tomorrow, we will check the details of the timeseries data.
