      * What TY thought
        * All activities which are submitted as 2021 DET effort should be described on this documents.
        * It will be based on white paper 2020 and KAGRA O4 readiness.
        * 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.
    * IMC Commissioning
      * Current IMC control signals on DGS are contaminated by circuit noise.
      * Important thing is that contamination is occurred only on DGS signals or also on real analog signals

   {{{
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”.

     * [[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?

      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”.

      • (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)

    • pyCBC trigger list for O4a data (Narikawa)
      • (yamaT) can we include the trigger information by pycbc, in the summary page?

      • 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.
