| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 1.64 | 0.163 | 100.0 |
| T < 1 s | 1.42 | 0.141 | 79.7 |
| T > 1 s | 0.59 | 2.8 | 20.1 |
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.
