| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 50.33 | 0.193 | 100.0 |
| T < 1 s | 50.06 | 0.197 | 99.2 |
| T > 1 s | 4.51 | 1.4 | 0.8 |
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.
