Notes. The quantities are the same as in Table A.1. The numbers in parentheses indicate the uncertainty on the last digit.
Event peaks before this date and the event properties are only computed using the time period considered in this paper.
Event peaks after this date. For event properties computed from a more appropriate time period, see Bramich & Nielsen (2018).
