Trajectories and target magnetosheath interval. Panel a shows the top view (xy-plane), panel b shows the side view from the dawnside (xz-plane), and panel c shows the view from the back (yz-plane). MASO coordinates are used. The BepiColombo MSB2 and MSB3 trajectories are respectively shown with a solid red and solid blue line, and the PICAM measurement time frames are indicated in rectangles. Models for the magnetopause and bow shock are illustrated by the black dashed (Winslow et al. 2013) and black solid (Slavin et al. 2009; Winslow et al. 2013) lines at X, Y, Z = 0, respectively.
