Crater features diagnostic of oblique impacts: The size and position of the central peak

Using Magellan data, I have investigated two crater characteristics that have been cited as diagnostic of oblique impacts: an uprange offset of the central peak in complex craters, and an increasing central peak diameter relative to crater diameter with decreasing impact angle. I find that the offset distribution is random and very similar to that for high-angle impacts, and that there is no correlation between central peak diameter and impact angle. Accordingly, these two crater characteristics cannot be used to infer the impact angle or direction
