Jurnal paper issue
PTEP (2) : noise budget(K.Yamamoto) Check list, slack <<Analysis ON GOING>>
- Environmental part
- Acoustic noise : on going (PEM injection analysis, Washimi)
- Seismic noise : summarise the actual seismic nois during O3GK? (who?)
- OMC leg vibration : 12th - 16th Sep. ?
AC power lines : Coherence analysis is done (http://klog.icrr.u-tokyo.ac.jp/osl/?r=14848, Washimi])
- Magnetic noise : skipped in this paper?
Newtonian : seismic newtonian -> from PTEP1 (or Francisca?) / water fluid newtonian -> skipped / air density -> skipped
- Line noise investigation
violin mode : Fitting analyisi is done (http://klog.icrr.u-tokyo.ac.jp/osl/?r=14886, Washimi)
- Environmental part
PTEP (3) : CAL, DET, PEM, GIF (Yokozawa) <<Referee comments>>
Acoustic injection paper (Washimi) <<Analysis Almost DONE>>
