      * (Yuzurihara) read BLRMS data and made the several plots with 1% and 99% percentile.
      * When KAGRA will be locked as observation mode?
       * hopefully after july, there will be lock trial for two monthes(?)
      * When you set the 1% criteria, always you throw away the 1% data?
       * We might need to consider the better procedure to care that point.
