| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 3.02 | 0.164 | 100.0 |
| T < 1 s | 2.61 | 0.152 | 87.3 |
| T > 1 s | 0.94 | 3.7 | 12.7 |
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.
