| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 4.29 | 0.723 | 100.0 |
| T < 1 s | 2.31 | 0.205 | 21.9 |
| T > 1 s | 4.24 | 3.4 | 78.0 |
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.
