| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 0.97 | 1.071 | 100.0 |
| T < 1 s | 0.51 | 0.273 | 15.3 |
| T > 1 s | 1.22 | 4.2 | 84.6 |
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.
