a, b display the bulk velocities of O+ and O2+ in the MSE frame, respectively. The grey shaded regions in (b), marked with the labels “c”, “d” correspond to the time intervals for the velocity distributions shown in (c, d). These panels illustrate the measured velocity distributions of O2+ in the \(V{x}_{{MSE}}-V{z}_{{MSE}}\) plane at the times 13:26:08, and 13:27:16, respectively.
