Table 3.
Statistics related to five groups (as listed in Section 3.3) of optimal γ found.
| Group | 1 | 2 | 3 | 4 | 5 | Total |
|---|---|---|---|---|---|---|
| γ range (×10−7 km−1) | 0.01–0.3 | 0.3–0.6 | 1–10 | 0.01–10 | no γ found | |
| Nr. of events | 12 | 6 | 2 | 7 | 4 | 31 |
| Median γ (×10−7 km−1) | 0.17 | 0.45 | 8.21 | 2.10 | 1.33 | |
| 95 perc. γ (×10−7 km−1) | 0.07–0.27 | 0.36–0.50 | 7.70–8.73 | 0.31–4.75 | 0.08–8.05 | |
| Mean v0 − w (km s−1) | 389 | 564 | 74 | 151 | 597 | 376.0 |
| 95 perc. v0 − w (km s−1) | 64–1112 | 226–1011 | −57–206 | 30–390 | 55–1812 | 4–1440 |
| Mean TTerr (hours) | 3.08 | −13.16 | −8.16 | −5.52 | 0.21 | −3.10 |
| Mean |TTerr| (hours) | 5.50 | 14.04 | 22.12 | 6.83 | 21.77 | 10.62 |
| 95 perc. TTerr (hours) | −6.18–10.80 | −27.43–1.11 | −29.17–12.86 | −17.60–3.75 | −39.67–25.29 | −33.49–17.76 |
Notes. The first row gives the number of CMEs for each group, the second row gives the median optimal γ, the third row gives the 95th percentile range of the found optimal γ, the fourth row gives the mean difference in v0 − w, and the fifth row gives the 95th percentile range of the difference in v0 − w. Transit-time errors (TTerr = TTDBEM − TTOBS) are calculated with γ values corresponding to the normal, operational DBEMv3 mode, where the sixth row gives the mean value of TTerr, the seventh row shows the mean absolute value of TTerr, and the eighth row gives the 95th percentile range of TTerr. The last column shows the statistics for all events together (total).
