Contributions to the total core mass for 1 and 100 km at 39 au (upper left and right respectively) and 1 and 100 km at 10 au (bottom left and right respectively) for a high resolution run of N = 10⁵ pebble swarms. The y-axis indicates thesize range of pebbles and the x-axis the distance from the core center. All the pebbles in a certain pixel with width Δr and height Δs are counted and weighted with respect to M_t, the total core mass. The mass contribution is shown by the color bar.
