| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 7.03 | 0.371 | 100.0 |
| T < 1 s | 6.63 | 0.352 | 88.8 |
| T > 1 s | 2.42 | 2.0 | 11.2 |
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.
