| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 2.10 | 1.128 | 100.0 |
| T < 1 s | 1.19 | 0.536 | 44.4 |
| T > 1 s | 1.98 | 2.4 | 55.6 |
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.
