| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 49.79 | 0.382 | 100.0 |
| T < 1 s | 49.74 | 0.387 | 97.9 |
| T > 1 s | 7.53 | 1.6 | 2.1 |
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.
