Delineating ricochets from roll-outs and stops {#sec:delin}
----------------------------------------------

Photographs of three different impact craters are shown in Figure \[fig:craters\]. These photographs were taken from above the sand tray looking downward and after the impacts. Using the impact crater morphology, we classified an impact as a [*ricochet*]{} if there was a clear gap between a primary crater and a secondary one, as shown in Figure \[fig:crater\_ricochet\]. An impact was classified as a [*roll-out*]{} if the
