Plots similar to those presented in Fig. 5, showing the disturbance connection times as a function of the longitudinal separation angle. Here an expansion speed of 800 km s⁻¹ and α = 0.8 are used in both panels. The black contour lines show the evolution of M_A values for different angles and times. The M_A were calculated using two different coronal models for the variation in density with the heliocentric distance. For the left panel, we used the Saito model and for the right panel, we used the Newkirk model.
