      * K1:VIS-ITMX_F3_LVDTINF_GAS_{IN1,OUT} have glitches.
      * It seems to occur around AA chassis. (AA and cable replacement didn't help to improve situation).
      * We will try to find glitches on other channels on the same ADC board.
      * This channel should be added to Omicron search on SummaryPages.
    * DQR progress
      * [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=13721|JGW-G2213721]]

  * 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.

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

    * CAGMon results
      * [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=12481|slide]]
    * O3 data replay

      * 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.
