| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 4.27 | 0.307 | 100.0 |
| T < 1 s | 4.26 | 0.304 | 94.6 |
| T > 1 s | 1.08 | 1.5 | 5.3 |
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.
