Notes. All tables: column densities are in units of 1022 atom cm-2; the normalization of the blackbody is in units of 1037 erg s-1 for a distance of 10 kpc, the cut-off power law normalization for the ADC emission is in units of photon cm-2 s-1 keV-1 at 1 keV. 90% confidence uncertainties are shown.
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.
