Notes. The time delays are expressed in days with respect to the observer’s frame of reference unless otherwise stated. The estimated errors are 1σ standard deviations. For ICCF, we also show the maximum correlation coefficient in parenthesis.
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.
