Notes. We report the effective exposure time after filtering periods of high count-rate and the background-subtracted count rate in the 1.5– 8.0 keV energy bandfrom the ellipse of Fig. 2, excluding point sources PS1 and PS2.
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.
