Number of the flow lines that cross the spheres at a distance of 800 AU (solid line), 500 AU (dotted), and 300 AU (dashed line) from the star vs the astrospheric longitude ϕ for three cases (in order from the top): V = 0.5 km s⁻¹, B = 7 µG (model 4), V = 2 km s⁻¹, B = 7 µG (model 5), and V = 10 km s⁻¹, B = 7 µG (model 9). For clarity, the data were averaged over 3° longitude bins. Boundaries of the R, L, and T sectors are marked by vertical dash-dotted lines.
