Relative velocities were calculated as the ratio of the mean velocities at t = 3–5 sec and t = −60–(-50) sec, where the encounter was defined as t = 0. Comparisons were performed using an ANOVA test corrected post hoc for multiple comparisons using Tukey’s HSD test. Single and double asterisks denote significant differences (P <0.05 and P <0.01, respectively). (TIF 396 kb)
