Noise investigation (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.

- Should clarify who will do each item (though personal name itself is not described on this documents).
Should show the rough timeline for R&D tasks.

SummaryPage construction
- The 1st version is already constructed on test directory.
We can apply it for product environment because current SummaryPage is not valid.
- lvalert test
- lvalert itself works well.
- Next step is receiving alert.
- We need to ask LIGO people about alert format etc.
- PMC/IMC commissioning
- Due to a lot of troubles, we haven't achieved IMC locked yet.
- We may start some kind of commissioning from Mid or Late of April.
- Meeting time in the next FY
- TY will circulate doodle poll.
- Progress of hveto analysis
20210317 (Thu.)
- O3GK paper
- hveto cross-check
- Checking Omicron parameter remains.
- Required re-run for whole two weeks.

- Merging short segments is not required.
- GEO data analysis
- It can be done by someone form Tagoshi-san's group.
- hveto cross-check
- O4 preparation
- Kamioka cluster
- It's pending due to the recovery work of power outage.
Takeover about Omicron, hveto, GlitchPlot
- Takeover itself is done.
- TY is finding candidate person of each pipelines toward O4.
- Omega-scan test
- Installing on Kashiwa
- lvalert test
- It's works well on k1det1
SummaryPage update
- The 1st version of VIS page is constructed.
- It's being checked by Miyo-kun.

- It is not locked yet because of some troubles.
- Kamioka cluster
20210225 (Thu.)

- Progress of O3GK paper
- O4 preparation
- Minutes
- Progress of O3GK paper
- Chihiro re-analysis with proper science segment for omicron triggers.
- A part of Kihyun's analysis is done.
- Cross-check can be done. But not start yet.
DetChar cluster in Kamioka
- OS installation for master node was done.
- Omega-scan test
- Installation for Kashiwa cluster was done.
- Error is occurred on gwdatafind.
- LVAlert
- Progress of O3GK paper
20210218 (Thu.)
- 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.
- 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.

- Progress of O3GK paper
Omicron trigger transfer: Kamioka -> KISTI, it is postponed.
- Young-Min asked KISTI administrator.
- GW-search triggers have not been served yet.
- 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)
- 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.
- DQ state vector (Yamamoto)
- Progress of O3GK paper

- 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)
- 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.

- Announcement
LVK DetChar call will be held (Jan. 25 19:00 JST, KST)
- Progress of O3GK paper
- CAGMon results
- O3 Data replay
- Announcement
- 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
- 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.
- Progress of O3GK paper
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.
- Model update will be finished soon.
- Progress of O3GK analysis
