* 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 * http://klog.icrr.u-tokyo.ac.jp/osl/?r=16082 * Master node installation is done. * SummaryPages * LVAlert * Omega-scan test * ----- === 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. * 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. |

=== 20210204 (Thu.) === * Agenda * Progress of O3GK paper * O3 data replay * O4 requirement * Minutes * 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. |

=== 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) * [[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. |
