Notes. The first section lists pre-event ellipsoid cone CMEs, with their insertion date and time at 0.1 au, latitude (Lat), longitude (Lon), major and minor angular half widths (ωmajor, ωminor), tilt angle, and insertion speed. The second section provides the details of a single post-event ellipsoid cone CME. The third section specifies the injection time, location, half width ω and speed of the shock waves. The final section describes the main-event spheromak CMEs, with the spheromak-specific parameters being its radius, helicity sign, and magnetic flux. Both the spheromak and the ellipsoid CMEs are injected with a uniform temperature of 8 MK and density ρ = 10−18 kg m−3.
