Temporal variations caused by Earth tides.
All available traces stacked into 25 bins according to their relative hour within one lunar tidal period of 24.8412 hours.
This period involves two high and two low tides, so if there is periodicity in the seismic velocities the signals are expected to follow similar pattern.
