View of the ecliptic plane from solar north of the orbital configuration of the four inner planets (plotted as spheres), the SoHO spacecraft, and the STEREO spacecraft (symbols). The Earth position is fixed to the bottom of the figures. The extent of the camera field of view in the ecliptic plane used in the triangulation of the CME pressure wave are plotted for each case. The direction of propagation of the CME is shown as a color-coded cone of fixed longitudinal extent. These directions of propagations were derived by the HELCATS project using heliospheric imaging (except for the 2014 Sep. 01 case, in which the coronal shock nose propagation direction was used).
