| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 11.06 | 0.341 | 100.0 |
| T < 1 s | 10.49 | 0.324 | 95.0 |
| T > 1 s | 2.36 | 1.7 | 5.0 |
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.
