Global distributions of MAVEN orbits used in this study. (a–c) Total orbits (N_sc). (d–f) Crossings of discontinuities between the magnetosheath and Martian induced magnetosheath with λ₂ ∕λ₃ ≥ 3 (). (g–i) Ratio of to the total crossings (N_B). (j-l) Ratio of to the total crossings. The distributions from top to bottom are in X–Y, X–Z, and X–R planes in the MSO coordinates, respectively. The black dashed circles stand for Mars. The black solid curves stand for the MPB from Trotignon’s model (Trotignon et al. 2006).
