| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 2.36 | 0.475 | 100.0 |
| T < 1 s | 1.63 | 0.182 | 41.6 |
| T > 1 s | 1.70 | 3.7 | 58.4 |
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.
