My primary source for meteorite craters was Expert Data-base on Earth Impact Structures (EDEIS) of Institute of Computational Mathematics and Mathematical Geophysics SB RAS, Tsunami Laboratory, Novosi¬birsk, Russia. I consid-er, from user experience, EDEIS as most reliable of all sources available in meteorite crater data.
