Comment to Seismic and Acoustic measurement at TAMA FC (Click here to view original report: 2989)

I compared the seismic data and the microphone data, with KAGRA at the same time.
Seismic data of KAGRA is under OMC chamber and the microphone is in the IMC refl.

The large peak at one-handed several-tens Hz of the seismic data is the self-noise. (data sheet)
