Recovery of the estimated average velocities by changing the number of arrival time data used in the analysis: a 1250; b 4393; and c 6414, which are about one-half, twice, and three times the number used in the main results, respectively. d MAE variations in the sample sizes for the estimation methods. The colored lines in ac are the same as those in Fig. 4
