| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 4.51 | 0.596 | 100.0 |
| T < 1 s | 2.86 | 0.311 | 53.6 |
| T > 1 s | 2.19 | 2.1 | 46.4 |
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.
