  - 4.5 Hz peak of IMC
  - Modified IMC page on SummaryPage
- 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)

Task list for the authorship 2024 (not fixed yet)

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)

  - 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.

   * The scale of histogram was changed. The apperance looks consistent with the dedicated summary page and the YamaT-san's [[https://gwdet.icrr.u-tokyo.ac.jp/~controls/misc/html/binaryRanges_o4a.html|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 [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=15747|Progress report]]
  * Line investigation (Samurai)
   * Reading Fscan paper for past observation run (S6, O1, O2). The report will be done in the future meeting.

   {{{
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.

     * (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.

    * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=28498|model update of k1detdq0]] This is bug fix of production of online data quality state vector related to DAC saturation.
    * The hardware test will be done this week an next week.
   * Tool to evaluate Gaussianity (Yamamura)
    * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=28519|Relaunch of GauCh]]
    * The codes were uploaded at [[https://git.ligo.org/yamamura/gauch|git repo]]. The preparation of brief documentation is ongoing.
   * Classification of glitch noise (Shikano, Oshino)
    * They restarted this project. The report will be done soon.
   * Provide the dedicated summary page for O4a of KAGRA (Uchikata) [[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.

     * 70 Hz glitch was not real glitch. When we apply the hight pass filter with 10Hz or use DISPLACEMENT channel, the glitch disappeared.
     * (YamaT) In the end, should we use which channel? h(t) channel with high pass filter or DISPLACEMENT channel?
     * (Yuzu) h(t) channel will be straightforward.
     * (YamaT) If the analysis method is affected by the difference of waveforms, we will obtain the different results, such as SNR. Hveto result depends on magnitude of SNR (by threshold).
