Maximum total radial acceleration, [mm s^-2] of particleson the equator of the fictitious model asteroids. Each row corresponds to a different asteroid model a) to d) perpendicular model with P_rot = 6 h, e) to h) perpendicular model with P_rot = 3 h, i) to l) aspect 45° model with P_rot = 6 h, and m) to p) aspect 45° model with P_rot = 3 h). Each column corresponds to different heliocentric distances. The maximum acceleration is calculated by finding the maximum value along the longitude on the equator for the given asteroid diameter D and particle radius r_a. The blue dashed lines and red solid lines indicate olivine and magnetite, respectively. The thickness of the contour increases as the acceleration value increases for fixed contour levels . Negative (inward) accelerations are not drawn.
