(a) Time delay between lower energy VDA extrapolated to higher energies of DME events and the fitted higher energy arrival times by energy. (b) Distance from initial release of particles and higher energy release of particles versus particle energy for DME events. Numbers in panels a and b indicate the event number for each DME event listed in Table 1. Idealized Parker spiral magnetic fieldlines colored by the maximum energy of particles being released at that heliospheric distance (D_x), neglecting the height of initial particle release (D₀), for: (c) DME events and (d) non-DME events. Diamonds in panel c denote the location of E_max release for the event, with the length of each Parker spiral fieldline extending to the location of Solar Orbiter for a given event (solid line). The dashed spiral in panel c extends from the location of Solar Orbiter to the computed location of maximum release energy for event 19. Panels c and d are oriented such that the location of the associated flare site would be directed along the positive x-axis, denoted by the purple arrow.
