Fig. 2.From: Ion acceleration by multiple reflections at Martian bow shockOverview of the MEX orbits during seven traversals given in Table 1. The traversal when the multiple ring-like distribution was observed is drawn by using solid lines with grey circle marks every 10 min and otherwise using dashed lines with white circle marks every 1 hour. The dashed grey lines indicate the average position of the bow shock and magnetopause (Vignes et al., 2000). The unit RM is the Mars radius. Cylindrical is used in the top left panel. The orbit numbers (#1 to #7) are the same as those in Tables 1–3.Back to article page
