| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 0.65 | 1.295 | 100.0 |
| T < 1 s | 0.34 | 0.429 | 18.5 |
| T > 1 s | 0.77 | 2.6 | 81.6 |
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.
