  * Agenda
    * Progress of O3GK paper
    * O3 data replay
    * O4 preparation
  * Minutes
    * Progress of O3GK paper
      * hveto conf is same
      * segment is used as latest same science segments
      * definition of cutting end of segments is difference.
      * Channel list is used as on github's one.
      * Next step -> unifying cutting definition.
        * Kihyun will re-run omicron with new segment cutting definition
      * We need to merge veto segment from a lot of short ones to continuous one.

      * Multi-taper and Welch show similar results
      * Bayesline result is slightly different from results by other two methods.
      * Estimated values are enough for O3GK (search) paper.
      * LVK review of this work is necessary for publishing results.

  * Agenda
    * Announcement
      * LVK DetChar call will be held (Jan. 25 19:00 JST, KST)
    * Progress of O3GK paper
    * CAGMon results
    * O3 Data replay
  * Minutes
    * Progress of O3GK paper
      * Some difference between Kihyun's and Chihiro's results.
      * hveto setting should be tuned on conf file and re-run again.
      * GW search results will be provided 1-2 months later (?).
    * CAGMon results
      * [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=12481|slide]]
    * O3 data replay
      * LV requested the simulated data instead of O3GK data as KAGRA's data.
      * Auxiliary channels which has realistic coherence, coincidence etc are not available.
      * All multi-channel analyses cannot work well in such situation.
      * We need more discussion how do we join O3 data replay.

  * Agenda
    * Progress of O3GK analysis
    * O4 preparation
  * Minutes
    * Progress of O3GK analysis
      * Analysis itself was finished.
      * Results by Chihiro and Kihyun are now comparing.
        * => Some conf. is still difference.
      * At least after finishing paper work, omicron triggers should be shared on Kashiwa cluster for remote site people.
    * O4 preparation
      * Model update will be finished soon.
        * => After model update, suspension commissioning will be started.
      * SummaryPages seems to be stopped.
        * => Because of the channel name update by VIS model changes.
        * => Current situation of real-time model is slightly complicated. ITMY: Old model, others: new model etc.
        * => After finishing CRY measurements, all suspension models are unified.
