Frequencies above 10 Hz look good for all spectra.

Many spectra have peaks at 1 Hz on their vertical sensors that haven't been there at least the past few weeks - every HAM and every BSC suspension on Stage 1

Compared to the last check, ETMY Stage1's vertical sensors are much louder between 4 and 10 Hz, and seem to line up with the oscillations of the horizontal sensors. The horizontal sensors are also elevated between 4 and 6 Hz.
