Semi-major axis histogram under the presence of all planets for β = 0.02. Occupancy is the number of particles per 0.0005 au bin divided by solar distance of that bin and then normalised to background count (i.e. under the absence of resonances). Vertical dashed lines indicate the locations of several first order as well as the co-orbital MMRs (including a shifting factor to account for radiation pressure). Mercury and Mars show no and virtually no effect on dust migration rate at this particle size. Trapping and displacing by Venus and Earth MMRs is significant, while the trapping by Earth MMRs is much more pronounced (considering the logarithmic scale). Internal Jupiter MMRs cause displacement analogous to Kirkwood gaps, but shifted in location due to radiation pressure. Other particle β are given in Fig. A.3.
