| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 7.90 | 0.193 | 100.0 |
| T < 1 s | 7.20 | 0.191 | 98.9 |
| T > 1 s | 0.70 | 2.6 | 1.1 |
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.
