| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 7.05 | 0.379 | 100.0 |
| T < 1 s | 5.21 | 0.248 | 77.7 |
| T > 1 s | 3.05 | 2.5 | 22.3 |
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.
