Numerical results of the ICME structure at 1 AU as function of the initial parameters. Percentages of variation of arrival velocity (panel a), travel time (panel b), total extension (shock, compression region and the rarefaction zone; panel c), compression region extension (panel d), density jump at the shock front (panel e), and density drop in the rarefied zone (panel f) are presented. Percentage changes as function of the CME injection parameters are shown with green solid lines. The star symbols connected with dark-green solid lines are those changes obtained with the variation of the CME speed while plus symbols connected with light-green solid lines to those related to the CME mass-loss rate. Square symbols connected with black solid lines show the results obtained by changing the duration of the CME. Those changes related to the SW input parameters are shown in red solid lines: triangles connected with dark-red solid lines for the SW initial speed, and diamonds connected with orange solid line for the SW mass-loss rate.
