| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 5.21 | 1.711 | 100.0 |
| T < 1 s | 2.33 | 0.974 | 19.8 |
| T > 1 s | 4.79 | 2.1 | 80.2 |
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.
