| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 4.45 | 0.657 | 100.0 |
| T < 1 s | 3.81 | 0.506 | 66.7 |
| T > 1 s | 2.76 | 2.5 | 33.3 |
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.
