Impact speed and particle mass determined by the measurement-derived method used in the dataset (green circles and black stars), by the approximate method that assumed β ≡ 1 (blue triangles), and by the iterative method (red crosses) using the union subset. The second and third methods assumed an inflow speed of v_d = 26 km/s from the direction (l_He, b_He), and the iterative method further utilised the β-curve of adapted astronomical silicates (see Fig. 1). The measurement-derived values for impacts with v_msr < 3 km/s (black stars) most likely feature severely underestimated impact speeds and severely overestimated particle masses. We note that the horizontal axis quantifies the impact speed in the spacecraft frame and not the heliocentric speed.
