  - We need same test for ETMY model.
- Scattered light noise (Yamamura)
  - Investigation of scattered light noise in O4a
  - (oshino) why the double bounce occurred?
  - (yamaT) it's better to check both the feedback and error signal (OUT_DQ and IN1_DQ).
  - (oshino) PD signal might be helpful in the investigation. In POP_FORWARD, the scattered light was seen in the past.
- Noise hunting by machine learning and Hveto (Kyujin, Kihyun, Syifa)
  - KAGRA O4a hveto results (0524 ~ 0606) KAGRA O4a hveto results (0607 ~ 0619)
  - hveto shows the many triggers on the time the scattered light noise appeared
  - (yamaT) IPC glitch was taken care in this analysis? It's better to use SCIENCE segment + IPC glitch segment.
  - It is interesting to compare the glitch rate and the analysis result with and without IPC glitch segments.
  - Yuzurihara shared that segment with Kihyun.
- provide the dedicated summary page for O4a of KAGRA (Uchikata and Narikawa) O4a (LV)
  - O4a summary page
- pyCBC trigger list for O4a data (Narikawa)

- Generation of trigger list by pycbc (Narikawa)
  - Code test is ongoing by using the short 4096s data of O4a. The timeseries of chi square looks strange. They plan to apply the high pass filter, instead of window function.
  - (yamat) How do you decide clustering length?
  - (Narikawa) By software injection, we can evaluate how the SNR spreads and determine the clustering length.

      * DQ event validation
        * under discussion
          Probably we cannot provide so many veto segments.<<BR>>
          So at least one (hopefully a few) simple segments will be provided and uploaded.<<BR>>
          (e.g. Omicron triggered segments, Earthquake segments, etc.)
      * GraceDB issue
        * under discussion
          Full(?) access to GraceDB is opened for KAGRA people.<<BR>>
          Developing/importing GraceDB API tools is better to be done with DET and DAWG.

  * Agenda:
    * KAGRA readiness issue
      * State Vector definition
        * SV is provided on the real-time IFO control model.

        * Finally it should be summarized as a tech-report.
      * DQSEGDB capability

        * Files will be shared with LV by rsync+ssh method.
        * Accessing gwdet.icrr.u-tokyo.ac.jp from LIGO's DQSEGDB was already successfully.
      * Web page preparation
        * SummaryPage is opened also for remote site people.
        * Contents are being closed to LIGO's SummaryPage contents.
        * TY and Alex are now updating some softwares on k1sum0. So SummaryPage may become unstable next couple of days.
      * DetChar/DQ event validataion
        * We are now planning to provide DQ flags indicating earthquake, loud seismotion, etc. (See Kozakai-san's slide)

      * Low-Latency tools and GraceDB issues
        * Some tools used as low-latency ones in LIGO (Omicron, hveto etc.) are available.
        * We are waiting for the update of GraceDB authentication by LIGO.

     * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=28568|Investigation of scattered light noise in O4a]]
     * (oshino) why the double bounce occurred?
     * (yamaT) it's better to check both the feedback and error signal (OUT_DQ and IN1_DQ).
     * (oshino) PD signal might be helpful in the investigation. In POP_FORWARD, the scattered light was seen in the past.
    * Noise hunting by machine learning and Hveto (Kyujin, Kihyun, Syifa)

     * hveto shows the many triggers on the time the scattered light noise appeared
     * (yamaT) IPC glitch was taken care in this analysis? It's better to use SCIENCE segment + IPC glitch segment.
     * It is interesting to compare the glitch rate and the analysis result with and without IPC glitch segments.
     * Yuzurihara shared that segment with Kihyun.

    * They tested the conda environment and configuration files for the production of the summary page. Except for the specific short time, they can generated the O4a summary page including duty cycle and inspiral range.
   * Generation of trigger list by pycbc (Narikawa)
    * Code test is ongoing by using the short 4096s data of O4a. The timeseries of chi square looks strange. They plan to apply the high pass filter, instead of window function.
    * (yamat) How do you decide clustering length?
    * (Narikawa) By software injection, we can evaluate how the SNR spreads and determine the clustering length.
