| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 7.34 | 0.185 | 100.0 |
| T < 1 s | 7.16 | 0.181 | 96.5 |
| T > 1 s | 1.82 | 3.1 | 3.5 |
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.
