        * These information are shared with LV via DQSEGDB.
      * Low-Latency tools and GraceDB issues
        * Some tools used as low-latency ones in LIGO (Omicron, hveto etc.) are available.
        * We are waiting for the update of GraceDB authentication by LIGO.
    * Offline DQ [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=11176}|Slides]]
