• Discussed on Feb. 28, 2024 (See also [kagra-detchar 02425])

Task List

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.
   Making summaries of observing runs is belongs to this task (Daily SummaryPages for site works should be included in 1.).

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.
