| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 13.50 | 0.741 | 100.0 |
| T < 1 s | 11.01 | 0.575 | 72.2 |
| T > 1 s | 7.06 | 1.9 | 27.8 |
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.
