| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 5.51 | 0.497 | 100.0 |
| T < 1 s | 4.91 | 0.459 | 82.7 |
| T > 1 s | 2.01 | 2.2 | 17.4 |
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.
