  * 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.
    * O3 data replay
      * Main purpose of O3 data replay is performing end-2-end test of low-latency pipelines (CAL, DET, DAS, etc).
      * LV will use real O3 data.
      * KAGRA provides simulated data (~80Mpc for BNS) because of too poor sensitivity of O3GK data.
      * We may need to inject GWs on software with consistency with LV's real events.
      * Frame work of software injection is already available.
    * SummaryPage
      * Updating VIS page.
      * It will be closed to LIGO's one.
    * LVAlert
      * k1det1 can be used for test.
      * Need personal account because we use personal DCC account for accessing GraceDB.
        * Ask LV people how to get common account on next LVK DET meeting.

        * Basic idea is omicron+hveto (same as O3GK)
        * Takeover should be done from Kozakai-san.

      * 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.

    * CAGMon results
    * O3 Data replay
  * Minutes
    * Progress of O3GK paper
      * Some difference between Kihyun's and Chihiro's results.

      * 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.


=== 20210107 (Thu.) ===
  * 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.

   * Online data quality state vector (YamaT)
    * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=28498|model update of k1detdq0]] This is bug fix of production of online data quality state vector related to DAC saturation.
    * The hardware test will be done this week an next week.
   * Tool to evaluate Gaussianity (Yamamura)
    * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=28519|Relaunch of GauCh]]
    * The codes were uploaded at [[https://git.ligo.org/yamamura/gauch|git repo]]. The preparation of brief documentation is ongoing.
   * Classification of glitch noise (Shikano, Oshino)
    * They restarted this project. The report will be done soon.
   * Provide the dedicated summary page for O4a of KAGRA (Uchikata) [[https://ldas-jobs.ligo.caltech.edu/~detchar/summary/O4a/|O4a (LV)]]
    * They tested the conda environment and configuration files for the production of the summary page. Except for the specific short time, they can generated the O4a summary page including duty cycle and inspiral range.
   * Generation of trigger list by pycbc (Narikawa)
    * Code test is ongoing by using the short 4096s data of O4a. The timeseries of chi square looks strange. They plan to apply the high pass filter, instead of window function.
    * (yamat) How do you decide clustering length?
    * (Narikawa) By software injection, we can evaluate how the SNR spreads and determine the clustering length.
