   {{{
1. Commissioning support : serving data monitoring tools for site commissioners.
  This task focuses on the support of the IFO lock trial and/or noise hunting based on the request from the interferometer commissioners.
  Support of analyses to measured data (e.g. noise projection to the DARM with measured noise and TFs) is also contained in this task.
  Specialized tasks for each subgroup should be applied for in the respective group task.

2. Production and validation of Online Data Quality State Vector (for O4b/O5 preparation.
  This task focusing on providing the online DetChar products such as the online DQSV and managing various reliable online flags.
  Developing real-time and guardian codes for providing such flags should be contained in this task.

3. Production and validation of Segment information for O4b/O5 preparation.
  This task focusing on providing low-latency/offline segments.
  Providing segment itself, evaluation of efficient channels to make segments, evaluating benefit of segments on GW searches
  and cooperation with CIT staffs to update segment contents on DQSEGDB are contained in this task.

4. Construction of DQR (Data Quality Report) and igwn-alert framework for O4b/O5 RRT activities.
  This task focusing on providing contents from KAGRA to DQR web pages which is merged with LIGO, Virgo and KAGRA.

5. Support of Data Analysis group to set Data Category criteria for O4b/O5 joint observing run.
  This task focusing on the support of the GW-search activities based on the each WG of DAC.
  Providing data category for the pipelines of each GW sources, providing veto segments
  and other noise information such as identified spectral lines are also contained in this task.

6. Managing DET computers and their environments.
  This task contains the computer environment construction for providing the DetChar products in the cadence of online/low-latency/offline.
  Managing dedicated servers for sharing DetChar products among LVK is also contained in this task.

=====
- Noise hunting in KAGRA commissioning.
    Obsolescent
    Noise *hunting* without IFO (hardware) experts is unrealistic.
    In this meaning, the most of noise *hunting* can be covered in "Commissioning support”.
    If the tasks are related to the noise *finding* for the purpose of providing veto segment,
    they can be covered in “Support of Data Analysis”.
   }}}
     * hveto analysis is contained in 1. in the case that there is some communication with onsite commissioners via klog etc.
       * It's also potentially contained in 5. in the case of providing veto-ed segments, correlated channels etc.
     * Providing Run SummaryPage is contained in 5.
       * Exact sentence as "Making Run Summary" should be added the description in 5.
        
   * Progress reports
     * Unify conda environment in Kamioka detchar computers, k1sum[01] and k1det[012] (YamaT)
       * start consideration about the system upgrade to new Debian system.
       * DET tools depend on the CDS tools and CDS tools are well managed on apt-repository.
       * Only a part of CDS tools can be available on Anaconda now.
     * DQR update (Yuzurihara)
     * Update contents of summary page (Oshino)
     * Combine DET computer resources into one DET cluster at Kamioka site
     * Related to segment files (Uchikata, Narikawa)
     * provide the dedicated summary page for O4a of KAGRA (Uchikata and Narikawa) [[https://ldas-jobs.ligo.caltech.edu/~detchar/summary/O4a/|O4a (LV)]]

     * pyCBC trigger list for O4a data (Narikawa and Uchikata) [[https://ldas-jobs.ligo-wa.caltech.edu/~detchar/summary/day/20240108/detchar/pycbc_live_medium/| O4a (H1)]]
       * 4000s data analysis is ongoing.
         * Processed time is a few hours
       * Used template is changed from BBH to BNS.
         * Trigger behavior is changed by used templates.
       * Generated triggers are in the text format.
         * If LIGO's XML (LW XML?) is available, it may be very easy to make various plots on SummaryPages.

     * [[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)
     * [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=15527|KAGRA O4a hveto results (0524 ~ 0606)]] [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=15632|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) [[https://ldas-jobs.ligo.caltech.edu/~detchar/summary/O4a/|O4a (LV)]]
    * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=28538|O4a summary page]]
   * pyCBC trigger list for O4a data (Narikawa)
    * (yamaT) can we include the trigger information by pycbc, in the summary page?

      • What is the frequency resolution?

      • Segment duration of 1800 s is a typycal value in continuous wave search? --> yes

      • Is is posible to real-time monitoring of 60 Hz?
      • What is the advantage to used fscan?

      • The result for O4a data is available on the web. Due to computational costs, we didn't use aux. channels.

    • Hveto analysis (Kyujin, Kihyun, Syifa)
      • By adding the high pass filter, the artificial glitches appeared, although there is no such glitches in Uchikata-san's results.

    • Omicron on K1 O4a Data (Chia-Jui) slide

      • They proposed the way to identify the IPC glitches. --> The way to identify the IPC glitches was already established.

      • Confirmation of the result is on-going.

      • The scale of histogram was changed. The apperance looks consistent with the dedicated summary page and the YamaT-san's result.

      • TODO: Inspiral range should be computed from the strain channel, not using the RANGE channel. That Range channel is used for the prompt report.
    • Hveto (Kyujin, Kihyun, Syifa)
      • The analysis result was explained in the meeting.
      • The high pass filter with 10 Hz or 15 Hz was applied for the Omicron analysis. The frequency range for Omicron should be tuned at the same time to mitigate the artificial noise in the Omicron triggers.
      • whale-like shape disappered in the histogram of Omicron triggers when we remove the segment of IPC glitch from the analysis.
      • Is there any suggestion to the interferometer experts? For example, which channels seems problematic.
    • Glitch investigation (Ishikawa)

      • Studying the Omicron pipeline and applying to the KAGRA's O4a data Progress report

      1. Commissioning support : serving data monitoring tools for site commissioners.
  This task focuses on the support of the IFO lock trial and/or noise hunting based on the request from the interferometer commissioners.
  Support of analyses to measured data (e.g. noise projection to the DARM with measured noise and TFs) is also contained in this task.
  Specialized tasks for each subgroup should be applied for in the respective group task.

2. Production and validation of Online Data Quality State Vector (for O4b/O5 preparation.
  This task focusing on providing the online DetChar products such as the online DQSV and managing various reliable online flags.
  Developing real-time and guardian codes for providing such flags should be contained in this task.

3. Production and validation of Segment information for O4b/O5 preparation.
  This task focusing on providing low-latency/offline segments.
  Providing segment itself, evaluation of efficient channels to make segments, evaluating benefit of segments on GW searches
  and cooperation with CIT staffs to update segment contents on DQSEGDB are contained in this task.

4. Construction of DQR (Data Quality Report) and igwn-alert framework for O4b/O5 RRT activities.
  This task focusing on providing contents from KAGRA to DQR web pages which is merged with LIGO, Virgo and KAGRA.

5. Support of Data Analysis group to set Data Category criteria for O4b/O5 joint observing run.
  This task focusing on the support of the GW-search activities based on the each WG of DAC.
  Providing data category for the pipelines of each GW sources, providing veto segments 
  and other noise information such as identified spectral lines are also contained in this task.

6. Managing DET computers and their environments.
  This task contains the computer environment construction for providing the DetChar products in the cadence of online/low-latency/offline.
  Managing dedicated servers for sharing DetChar products among LVK is also contained in this task.

=====
- Noise hunting in KAGRA commissioning.
    Obsolescent 
    Noise *hunting* without IFO (hardware) experts is unrealistic.
    In this meaning, the most of noise *hunting* can be covered in "Commissioning support”.
    If the tasks are related to the noise *finding* for the purpose of providing veto segment,
    they can be covered in “Support of Data Analysis”.
      • hveto analysis is contained in 1. in the case that there is some communication with onsite commissioners via klog etc.
        • It's also potentially contained in 5. in the case of providing veto-ed segments, correlated channels etc.

      • Providing Run SummaryPage is contained in 5.

        • Exact sentence as "Making Run Summary" should be added the description in 5.
    • Progress reports
      • Unify conda environment in Kamioka detchar computers, k1sum[01] and k1det[012] (YamaT)
        • start consideration about the system upgrade to new Debian system.
        • DET tools depend on the CDS tools and CDS tools are well managed on apt-repository.
        • Only a part of CDS tools can be available on Anaconda now.
      • DQR update (Yuzurihara)
      • Update contents of summary page (Oshino)
      • Combine DET computer resources into one DET cluster at Kamioka site
      • Related to segment files (Uchikata, Narikawa)

      • provide the dedicated summary page for O4a of KAGRA (Uchikata and Narikawa) O4a (LV)

      • pyCBC trigger list for O4a data (Narikawa and Uchikata) O4a (H1)

        • 4000s data analysis is ongoing.
          • Processed time is a few hours
        • Used template is changed from BBH to BNS.
          • Trigger behavior is changed by used templates.
        • Generated triggers are in the text format.

          • If LIGO's XML (LW XML?) is available, it may be very easy to make various plots on SummaryPages.
