Compared the BS geophone signals to other suspensions.
And as reference, the second figure is the noise spectra analyzed about 2 years ago (same units).

ETMX geophone signals are so good!
SR3 geophone signals (set on the ground) seem to be good as well, except that H2 signal is not alive.

BS signals have bad noise level, especially H3... Debug is necessary.
