| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 55.76 | 0.282 | 100.0 |
| T < 1 s | 55.31 | 0.292 | 98.6 |
| T > 1 s | 6.88 | 1.6 | 1.4 |
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.
