Distance between the “gradient” path (green line) and the “topological” path (orange line) with respect to the eruptive path, as a function of the height (without including the GCS reconstruction). The purple dashed lines denote the difference between the radial path from the source region and the actual eruptive path. The gray shaded area indicates the error of the eruptive path. Lower panel: the angular separation to the eruptive path for all the events at 2.5 R_☉.
