NOTE: The diameter of Woodleigh is contentious - with interpretations ranging from 40 km to 120 km (Mory et al., 2000, Reimold & Koeberl, 2000). Based on the extrapolation of the central peak diameter the rim-crest diameter should be 92-109 km though this is not clearly evident in the geophysical evidence.
