Figure 6

The average residual distances (D) between the ellipse and the heliocentric distances of Earth and Mars, at the observed in situ shock arrival times, are plotted as function of the ellipse aspect ratio ar, for half widths of 46–60° heliospheric longitude as indicated by the colours. The CME direction is set to W45, the mean value derived from triangulation.
