Stack plot showing radial velocity as a function of time at (a) 31R_⊙, (b) 0.7 AU (orbital distance of SolO, and slightly farther away than the location of BepiColombo, at the time of the ICME), and (c) 1 AU (the orbital distance of STEREO-A and ACE), for the traces marked in Figure 7. The longitude (in degrees) of the traces is shown in the legend. Each profile is displaced by the preceding one by 1200 km/s.
