Two-dimensional cuts of the calculated gas kinetic temperature (on a log10 scale) in the four source models with the parameters given in Table 1. The black contour levels are at 250, 400, 800, and 1600 K. The streamlines have launch radii ranging from the sublimation radius Rsub to 25 AU. The calculations were stopped inside the cone with z/r = 20 where streamlines start to recollimate towards the axis and shocks may later develop. The wind density drops from right to left successively by a factor 4, , and 5. The wind temperature increases when the wind density drops, as a result of the balance between radiative cooling and heating by ion-neutral drift (caused by MHD wind acceleration).
