在Wisdom（2017）中，我提出了新的模拟陨石从与小行星带中主要共振相关的混沌区运输：ν6长期共振，与木星的3：1平均运动共振，以及与木星的5：2平均运动共振。我发现，观测到的下午多余的普通陨石（下午坠落的陨石数量大约是上午的两倍）与3：1共振的混沌运输相一致，与之前的报告相矛盾。在这里，我报告了一个额外的研究陨石的运输从ν6长期共振和3：1平均运动共振。采用改进的积分算法，研究了更多粒子的演化。我确认，下午普通彗星的过剩与3：1共振的运输是一致的。
In Wisdom (2017), I presented new simulations of meteorite transport from the chaotic zones associated with major resonances in the asteroid belt: the ν6 secular resonance, the 3:1 mean motion resonance with Jupiter, and the 5:2 mean motion resonance with Jupiter. I found that the observed afternoon excess (the fact that approximately twice as many meteorites fall in the afternoon as in the morning) of the ordinary chondrites is consistent with chaotic transport from the 3:1 resonance, contradicting prior reports. Here I report an additional study of the transport of meteorites from ν6 secular resonance and the 3:1 mean motion resonance. I use an improved integration algorithm, and study the evolution of more particles. I confirm that the afternoon excess of the ordinary chondrites is consistent with transport from the 3:1 resonance.
