Snapshots of the logarithmic number density (colour scale) and selected magnetic field lines for 15 variants in the parameter study. The green panels (top row) correspond to SSW, the grey panels (rows 2–4) to MSW; and the blue panels (bottom row) to FSW. The magnetic field strength increases from top to bottom within columns, and the temperature increases from left to right within rows. The colour scales are different for the different solar wind regimes.
