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”.

- Minutes
- Update contents of summary page (Oshino)
- 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.

- 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.

- 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)

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.
- hveto analysis is contained in 1. in the case that there is some communication with onsite commissioners via klog etc.
- 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)
