| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 6.38 | 0.278 | 100.0 |
| T < 1 s | 6.17 | 0.276 | 98.7 |
| T > 1 s | 0.69 | 2.0 | 1.3 |
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.
