| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 5.90 | 0.341 | 100.0 |
| T < 1 s | 5.20 | 0.301 | 85.0 |
| T > 1 s | 2.09 | 2.2 | 15.0 |
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.
