| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 1.89 | 0.734 | 100.0 |
| T < 1 s | 1.39 | 0.284 | 30.8 |
| T > 1 s | 2.01 | 2.6 | 69.1 |
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.
