Table 1.
Correlation coefficients between the corresponding travel times and rms of their difference.
| Type | corr | rms |
|---|---|---|
| [s] | ||
| Different noise components | ||
| (arc → o-i), o-i | 0.89 | 14.4 |
| (arc → mn), mn | 0.68 | 7.4 |
| (arc → e-w), e-w | 0.77 | 10.8 |
| (arc → n-s), n-s | 0.76 | 11.0 |
| Noise components suppressed | ||
| (arc → o-i), o-i | 0.99 | 2.9 |
| (arc → mn), mn | 0.81 | 1.6 |
| (arc → e-w), e-w | 0.97 | 2.2 |
| (arc → n-s), n-s | 0.96 | 2.5 |
Notes. Top part: Computed from the measured travel times (different averaging geometries imply different realisation noises). Bottom part: Travel times were smoothed with the Gaussian (standard deviation of about 4 Mm).
