Each plot shows the velocity profile of the associated model in the background color-coded and on top are the paths of the spacecraft with their respective in situ measured velocities. Next to the paths of the spacecraft, there are colored paths indicating the spacecraft (cf. Figure 2); yellow: SolO, red: PSP, black: STEREO-A and blue: ACE. In the online version of the article we also present a movie showing the inelastic propagation in process.
