| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 4.02 | 0.198 | 100.0 |
| T < 1 s | 3.44 | 0.169 | 86.8 |
| T > 1 s | 1.37 | 3.2 | 13.2 |
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.
