• PTEP (2) : noise budget(K.Yamamoto) Check list, slack <<Writing>>

  • PWT is writing the draft

• PTEP (3) : CAL, DET, PEM, GIF (Yokozawa) <<Referee comment>> JGW-P2011664

• Acoustic injection paper (Washimi) <<Submitted>> JGW-P2012122

  • Submitted to CQG on 2020/12/26, Awaiting Referee Reports

  • LIGO O3 PEM paper has been openrd in arXiv:2101.09935

• Lightening paper (Washimi) <<Submitted to CPC>> JGW-P2112426

  • CPC has discussed this issue and decided to ask me to make the data used in this paper to be playground data, because currently they have no definite criteria to judge which KAGRA data.
  • Washimi plan to hold a seminar in near future to explain this paper and playground-data application.

can be used in a shot-author-list paper.

• Fractal paper (with Virgo) <<Submitted to CPC>> JGW-P2112438

• Seismic NN paper (with Virgo) <<DRAFT CIRCULATION>>

• Reverberation time paper (Washimi+) <<Start writing>>

• ICA for E-run/O3GK (Kume, Yokoyama) <<Analysis ON GOING>>

• Portable PEMs (Yokozawa+) <<Start writing>>
