Notes. Midtimes are derived logarithmically, t = 10([log(t1 − t0)+log(t2 − t0)]/2), hereby t1.2 are the start and stop times, t0 is the Swift trigger time. Upper limits marked with a represent stacks of all observations in each specific filter that yielded only upper limits, to obtain deeper limits on the host galaxy.

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.
