| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 18.18 | 0.419 | 100.0 |
| T < 1 s | 16.59 | 0.369 | 87.8 |
| T > 1 s | 6.63 | 1.6 | 12.2 |
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.
