  1. The top three rows list the common initial parameters and the other rows list the different initial parameters. For the common initial parameters, from the second column to the right, they are the propagation direction, radius, magnetic field, number density, temperature, the magnetic, thermal and gravitational energies and the background solar wind speed along the direction at 18 and 220 RS, respectively. For different initial parameters, from the top to bottom, they are the CME’s initial speed, kinetic energy, total energy and the separation time between the launches of the two successive CMEs.
