Notes. The unabsorbed flux is given in units of 10⁻⁹ erg cm⁻² s⁻¹ (ObsID sorted in an ascending flux order). The parameters E_cut (cut-off energy), σ_Fe (the width of iron line), and kT_bb (the blackbody temperature) are in units of keV. Uncertainties are given at the 68% confidence.

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.
