Notes. “Exp” is the exposure time while expclean refers to the net exposure remaining after removing times affected by background flares from the specified instruments (MOS1+MOS2 or pn). Count rates are given for the 0.5−10 keV energy range for the different instruments (MOS1+MOS2, pn and ACIS). Superscript 1 means that only MOS1 was used. In the case of Chandra ACIS, the count rate is for the annular extraction region at the nucleus.
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.
