| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 1.85 | 0.494 | 100.0 |
| T < 1 s | 1.37 | 0.259 | 45.3 |
| T > 1 s | 1.38 | 3.1 | 54.6 |
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.
