| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 2.09 | 0.522 | 100.0 |
| T < 1 s | 1.82 | 0.421 | 67.9 |
| T > 1 s | 1.30 | 2.5 | 32.1 |
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.
