Notes.Dates are given in YYYY/MM/DD; t0 and t1 are in [MJD], while half-bin times are in hours; fluxes are in units of [10-6 ph cm-2 s-1] and the TS of the detection is indicated between parentheses; the significance S of the flux difference is in [σ]; the absolute values of the observed characteristic timescale τ (positive for decay, negative for rise) and the intrinsic one τint = τ/(1 + z) are given in hours.
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.
