Notes. The initial conditions are taken from the chaotic edges of the resonance in Fig. 1. The results are obtained with Orbit9 and Rebound/Mercurius for three different integration time steps: Δt = {1, 0.1, 0.01} yr. The upper rows show the percentage of objects entering a given neighborhood of Phaethon, UD, and YC. The middle rows show their first arrival times, and the bottom their median arrival times. These results are discussed in the main text.
