      - LLO https://git.ligo.org/noisecleaning_o4/frontend-nonsens/llo-online-cleaning
    - The output channels are available in the control rooms, for use with commissioning, and are the same channels that analysis pipelines will use.
  - ...
Scope of the Group to be established
- Organization?
  - Chia-Jui Chou from Natl. Yang Ming Chiao Tung U. will lead the group as the chief.
  - Will the group encompass all noise subtraction-related activities at KAGRA? (ICA+DeepClean+...)
  - Will the group focus specifically on areas that contribute to the commissioning timeline, i.e., low- or middle-latency?
  - or...
- Roles/Goals for each phase
  - During the commissioning period prior to participating in O4b observation
  - During the O4b observation
    - Q: Will the cleaned h(t) produced by this team be used as an official deliverable and released to the public?!
  - 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?
