| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 23.55 | 0.436 | 100.0 |
| T < 1 s | 23.20 | 0.405 | 87.6 |
| T > 1 s | 9.66 | 2.4 | 12.4 |
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.
