| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 6.93 | 0.487 | 100.0 |
| T < 1 s | 6.56 | 0.445 | 84.8 |
| T > 1 s | 2.77 | 1.7 | 15.2 |
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.
