Mercator projections of the Poynting flux (upper row), plasma velocity (middle row), and absolute values of Poynting flux components parallel to the unperturbed planetary field plus the small background field from stellar wind (bottom row). The results are shown at an altitude of one planetary radius above the surface. The left column displays maps for the open MS case (θ_B = 0°), the right column for the closed MS case (θ_B = 180°). Arrows indicate normalized angular components, and color contours denote radial components. Dashed red lines indicate the location of the OCFB.
