          * Found correlation between wind power and BNS ranges
          * OMMT1 doesn't (maybe) have Oplev. It's better to confirm what kind of sensors were coneected.
          * BNS range channel has ~2min latency. It may become better results by considering the latency in BNS range calculation.
      * IMC commissioning
        * Noise investigation ([[https://klog.icrr.u-tokyo.ac.jp/osl/?r=16928|klog]])
        * Correlation between IMC and MIC sometimes increase in spite of no change in microphone spectra.
        * Coupling coefficients may be changed in time.
      * Cross check of hveto results.
        * Kihyun's (KISTI) and Chihiro's (Kamioka) results were confirmed as consistent each other.
        * For O4 observing run, Kashiwa environment is also important for increasing machine power.
        * Requirement of machine power should be estimated soon (but it's strongly depends on the situation of O4 joining)
        * We plan to use 100-200 aux. channels and it's very helpful to analyze them at the same time for each pipeline.

      * K1:OPS-SIM_GAUSS3_OUT (simulated auxiliary channel)
    * O4 requirement
      * DQ state vector (Yamamoto)
        * Providing on real-time model.
      * Data Quality Report (Yuzurihara)
        * First step is to use lvalert in order to receive GW alert from GraceDB.
      * Transient Event validation (Kozakai)
        * Basic idea is omicron+hveto (same as O3GK)
        * Takeover should be done from Kozakai-san.
      * Category veto (Yamamoto)
        * At least CAT1 should be provided.
        * We need to convert to veto-definer file format.
      * Spectral lines investigation (Yokozawa)
        * Listing of VIS-derived peak frequencies.

    * Report from Burst search
    * Binary range evaluation with C20 offline h(t)
    * Progress of O3GK paper
  * Minutes
    * Report from Burst search
      *
    * Binary range evaluation with C20 offline h(t)
      * [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=12499|slide]]
      * 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.
    * Progress of O3GK paper
      *


=== 20210121 (Thu.) ===
  * 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.


=== 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.
