Notes. The reported EPIC instruments are those where the source was detected and a spectrum was extracted. The exposure times correspond to the duration of the observation after the subtraction of the flaring background, except for ObsID.0891802101, where no spectrum was available. The EPIC counts refer to the estimated source counts in all EPIC detectors in the 0.2–12 keV band.
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.
