Extended Data Fig. 3: Crater d/D increases as a function of distance from the center of Shoemaker crater.

Median crater d/D as a function of surface distance (red curve) and straight-line distance (grey curve) from the center of Shoemaker crater, showing an increase in d/D with both surface and straight-line distance from Shoemaker, similar to crater R (Fig. 2b,c). The trend is more prominent in surface distance (red curve) and shifted rightward compared to straight-line distance (grey curve). We find that both the median values of crater R and d/D with distance to Shoemaker crater asymptote at larger surface-distances compared to straight-line distances. The vertical black dashed line marks one Shoemaker crater radius.
