| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 8.51 | 0.338 | 100.0 |
| T < 1 s | 8.45 | 0.341 | 99.0 |
| T > 1 s | 0.78 | 1.7 | 1.0 |
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.
