| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 7.97 | 0.280 | 100.0 |
| T < 1 s | 7.72 | 0.278 | 96.2 |
| T > 1 s | 1.56 | 2.2 | 3.8 |
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.
