| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 26.55 | 0.240 | 100.0 |
| T < 1 s | 25.73 | 0.232 | 99.4 |
| T > 1 s | 2.05 | 2.1 | 0.6 |
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.
