| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 10.08 | 0.159 | 100.0 |
| T < 1 s | 9.29 | 0.150 | 98.3 |
| T > 1 s | 1.02 | 2.2 | 1.6 |
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.
