Properties for all normal CMEs and for all inverse CMEs (left and right, respectively). The colours represent different initial velocities (green: 400 km s⁻¹, red: 800 km s⁻¹, blue: 1200 km s⁻¹), while the line-styles represent different background wind densities (dashed: 4 cm⁻³, solid: 8 cm⁻³, dotted: 12 cm⁻³). From top to bottom, the y-axes represents the stand-off distance, the length of and the height of the separatrix of the CME, respectively. The x-axis in the first row represents the position of the shock, while the x-axis of the second and third rows represent the position of the centre of the magnetic cloud. Both columns have the same scale to facilite comparisons.
