(en) « Earth Impact Database: Manicouagan », sur Planetary and Space Science Centre (consulté le ) : « This revised diameter is the best estimate for the collapsed transient crater diameter (rim-to-rim dimension). Our previous diameters cited maximum damage diameter estimates. There is considerable confusion in the literature regarding the definition of "diameter". In the Earth Impact Database, we are striving to cite the collapsed transient crater value where possible. This can affect the order of size: for example, Sudbury's maximum damage diameter is ~260 km (as defined by the outermost ring diameter), while that of Chicxulub is ~240 km. However, the rim-to-rim diameter of Sudbury is less than that of Chicxulub's (130 versus 150 km, respectively). »
