          * OMMT1 doesn't (maybe) have Oplev. It's better to confirm what kind of sensors were coneected.
          * BNS range channel has ~2min latency. It may become better results by considering the latency in BNS range calculation.
      * IMC commissioning
        * Noise investigation ([[https://klog.icrr.u-tokyo.ac.jp/osl/?r=16928|klog]])
        * Correlation between IMC and MIC sometimes increase in spite of no change in microphone spectra.
        * Coupling coefficients may be changed in time.
      * Cross check of hveto results.
        * Kihyun's (KISTI) and Chihiro's (Kamioka) results were confirmed as consistent each other.
        * For O4 observing run, Kashiwa environment is also important for increasing machine power.
        * Requirement of machine power should be estimated soon (but it's strongly depends on the situation of O4 joining)
        * We plan to use 100-200 aux. channels and it's very helpful to analyze them at the same time for each pipeline.

  * Hveto (Shifa)
   * By changing cutoff frequency of 8 or 12Hz, they checked the Hveto results and found the artificial glitches around 10Hz.
   * When they apply the HPF with 6 Hz or 4 Hz, the artificial glitches around 10Hz disappeared.
   * (YamaT) Do you know the design of HPF (butterworth?)?
   * (Uchikata) Minimum frequency of Hveto should be larger than the cutoff frequency of high pass filter in Omicron.
    * (YamaT) It might make the ripple.
   * (Yuzu) You can analysis the Omicron triggers with the higher cut-off frequency.
  * Glitch analysis (Ishikawa)

   * (Chia-Jui) How do you set-up the Omicron configuration files? --> Same as commonly used one.
   * (Chia-Jui) What was the typical SNR of 300-500Hz? --> SNR 6~10? He didn't have a clear answer. He will check it.
  * Glitch analysis (Chir-Jui)
   * Omicron analysis without high pass filter was done.
   * In page 7, there were gaps due to the exceed of threshold of glitch rate. At that time, Omicron failed due to the error.
   * We confirmed the goal of the Detchar activity is to contribute the sensitivity or noise hunting of KAGRA.

   {{{
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.

=====
- 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

      • 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)

    • 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.
