Visualization of the components used for the impact parameter calculation, where r₁, r₂ and d are determined on the last frame before the aggregates get in touch. The dotted line represents the momentary projected trajectory of the smaller aggregate relative to the center of mass of the larger aggregate (white cross). The offset trajectory through the center of mass of the larger aggregate is marked with a dashed line. The distance d between the center of mass of the larger aggregate and the momentary projected trajectory of the smaller aggregate is visualized with a thin line.
