Comparison of the inferred particle release times with the arrival time of the EUV wave at the spacecraft field line footpoints. The ⋆ markers show the angular distance of the EUV wave from the AR. The release times for electrons and protons are shown by × and + markers for each spacecraft. The angular distance of the magnetic footpoint from the active region for each spacecraft is shown by the vertical bars, which assume an uncertainty of ±5 deg.
