- Online data quality state vector (YamaT)

  - 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

  - Relaunch of GauCh
  - The codes were uploaded at git repo. The preparation of brief documentation is ongoing.

  - They restarted this project. The report will be done soon.
- Provide the dedicated summary page for O4a of KAGRA (Uchikata) O4a (LV)
  - 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.

     * (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.
   * provide the dedicated summary page for O4a of KAGRA (Uchikata and Narikawa) [[https://ldas-jobs.ligo.caltech.edu/~detchar/summary/O4a/|O4a (LV)]]

    * 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.
