Magnetic and velocity fields with their perturbations from the average shown with time progresses from right to left. Inbound and outbound crossings are marked with purple and cyan vertical dashed lines, respectively. (a) Magnetic fields. (b,c) Magnetic field fluctuations from the averages in the R − T and R − N planes, respectively. (d) Ion bulk velocity V_R component. (e) Ion bulk velocity V_T and V_N components. (f,g) Velocity field perturbations in the R − T and R − N planes, respectively.
