| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 1.76 | 0.195 | 100.0 |
| T < 1 s | 1.50 | 0.163 | 81.0 |

Significant height and period are derived from a zero-crossing analysis of the wave signal after the arrival time of the p waves.
They are the averages of the highest third of the waves.
