      * Due to IPC glitch, the locked segment will be devided into short segments. They evaluated the fraction of the short segments. The actual threshold is necessary to be determined in future. [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=16430|slide]]
      * The current favor is 256 s. When we applied this threshold, we will exclude 1% data from the science mode. We need to collect the requirements of each pipeline.

      * We need to update other scripts if we change the segment name. Developers or maintainers, please check your code.
     * It's better to keep the code in the [[https://github.com/gw-detchar/tools|GitHub repository]] up-to-date. Remember to push the code after you modified it or confirmed it's stable.
     * The line monitor is working well during the holidays. [[https://gwdet.icrr.u-tokyo.ac.jp/~controls/LineMonitor/day/today/|web]]

    • Segment file

      • The segment name of the IPC glitch was changed from K1-DAQ-IPC_ERROR to K1-DAQ_IPC_ERROR. klog

      • Due to IPC glitch, the locked segment will be devided into short segments. They evaluated the fraction of the short segments. The actual threshold is necessary to be determined in future. slide

      • The current favor is 256 s. When we applied this threshold, we will exclude 1% data from the science mode. We need to collect the requirements of each pipeline.
    • Noise subtraction pipelines (Chia-Jui Chou)

      • The common goal is to subtract the noise.
      • it's important to test the long term stability.

      • Summarize the lockloss count labeled by the SYS_LOCKLOSS guardian klog table

      • Categorization by the behavior of POP90 before the lockloss klog

    • Segment file

      • The segment of K1-GRD_PEM_EARTHQUAKE is already available on DQSEGDB. For other new segments will be available at DQSEGDB. (git issue)

      • Name convention issue came up. Plan: K1-DAQ-IPC_ERROR --> K1-DAQ_IPC_ERROR. Before releasing this segment, we have a chance to change the name.

      • We need to update other scripts if we change the segment name. Developers or maintainers, please check your code.

    • It's better to keep the code in the GitHub repository up-to-date. Remember to push the code after you modified it or confirmed it's stable.

    • The line monitor is working well during the holidays. web
