| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 36.12 | 0.220 | 100.0 |
| T < 1 s | 36.49 | 0.216 | 99.7 |
| T > 1 s | 1.63 | 1.4 | 0.3 |
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.
