Noise Subtraction subgroup

• Pre-meeting
  • Date/Time: Tuesday, November 5th, 2024, 1600-1800 JST (0700-0900 UTC)
  • Connection Info.: Zoom1
  • Agenda
    • Brief Overview of Noise Subtraction Activities
      • Application to GW experiments/analysis
        • What can be accomplished? How effective is it in improving sensitivity/analysis etc.?
      • Activities at KAGRA

        • who, what, features, current status, future plan?

          • DeepClean

          • ICA (Independent Component Analysis)
          • Other ongoing initiatives?
            • Has each research unit or search pipeline been developing noise subtraction optimized for their specific needs?
      • Other efforts within LV(K)
        • NonSENS (NON-Stationary Estimation of Noise Subtraction)
        • ...

    • Scope of the group to be established

      • Organization?
        • Chia-Jui Chou (Natl. Yang Ming Chiao Tung U.) will lead the group.
        • Will it encompass all noise subtraction-related activities at KAGRA?

        • Will it focus specifically on areas that contribute to the commissioning timeline, i.e., middle-latency?

      • Roles/Goals for each phase
        • during the commissioning period prior to participating in O4b observation
        • during the O4b observation
        • for future phases O5/O6
      • How collaborate with on-site commissioners/IFO experts?
        • e.g.,
          • Commissioners may request specific noise subtraction, such as subtracting noise in channel-A using auxiliary channel-B?
          • Commissioners may manage a safe channel list?
          • ...
        • What considerations should guide us as we progress? How should we work with the team?
