- What TY thought
- All activities which are submitted as 2021 DET effort should be described on this documents.
- It will be based on white paper 2020 and KAGRA O4 readiness.
- Should clarify who will do each item (though personal name itself is not described on this documents).
Should show the rough timeline for R&D tasks.
- O3GK paper
- We need to continue to discuss with GEO people about GEO data analysis.
- IMC Commissioning
- Current IMC control signals on DGS are contaminated by circuit noise.
