It is impossible to be absolutely correct in preparing chronologies like this. We apologize if we missed any important works or for incorrect presentation of the material. This was the result of the authors' lack of knowledge, and the responsibility is only the authors'. Fortunately the Discovery database will continue to be maintained in the future. Any corrections and suggestions are welcome and will be accepted with gratitude by the PDG and COMPAS groups.
