| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 3.26 | 0.189 | 100.0 |
| T < 1 s | 2.97 | 0.178 | 96.7 |
| T > 1 s | 0.66 | 3.0 | 3.3 |
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.
