Notes. Comparison of statistics for found optimal γ depending on the different windows for the perfect vtar from 10 to 100 km s−1. All results were obtained with the largest γ range, 4, and all columns are for perfect TT and vtar, except the first column (only TT), which was only computed for perfect TT without the constraint in vtar. All results for perfect TT and vtar are calculated for the two observed arrival speeds: mean and peak vOBS. The first row shows the mean optimal γ in km−1 for all events where optimal γ was found, the second shows the median optimal γ (km−1), the third and fourth rows show the lower and upper 95th percentiles (km−1), the fifth row shows the total number of optimal γ found, the sixth row shows the percentage of events (out of 31) that found an optimal γ, and the last row gives the number of events that did not find any optimal γ. The values in the selected window with |vtar − vOBS|≤ 75 km s−1 and mean vOBS presented in this study are in bold.
