  • O3 data replay
    • K1:OPS-SIM_GAUSS1_IN1 (simulated error signal)
    • K1:OPS-SIM_GAUSS1_OUT (simulated h(t) )
      • gaussian noise as floor level
      • Some spectral lines (cal lines, violin mode, power lines)
      • Simulated glitches.
    • K1:OPS-SIM_GAUSS3_OUT (simulated auxiliary channel)

20210128 (Thu.)

• Agenda
  • 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)

    • 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

    • 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.
