Notes. The quantities are the same as in Table A.3. The numbers in parentheses indicate the uncertainty on the last digit.
(a)
Event peaks after this date. For event properties computed from a more appropriate time period, see Bramich & Nielsen (2018).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
