Top: distance of deceleration by CE momentum transfer down to 1 km s^-1 as a function of the initial temperature and speed of the flow. Distances are in AU (color scale and iso-contours). Other parameters are as in Fig. 7. Bottom: fraction of ions experiencing charge-exchange per AU traveled distance of the bulk flow, computed where the bulk speed is reduced to 1 km s^-1. Fractions are in percent per AU (color scale and iso-contour).
