Notes. Measured recurrence time between observed bursts is Δtrec. The effective exposure time, Texp, takes into account all the instruments observations. In Fig. 10 the triangles corresponds to Δtrec/(N + 1), with N being the number of the expected missed bursts.

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.
