| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 6.95 | 0.248 | 100.0 |
| T < 1 s | 6.12 | 0.227 | 95.9 |
| T > 1 s | 1.58 | 3.1 | 4.1 |
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.
