Notes. Γ_e is the classical Eddington parameter, u_∞ is the maximum jump speed used to determine the X-ray characteristics, log₁₀(f_X) is defined as 16e_s² with e_s the X-ray volume filling factor. L_X/L_bol is the X-ray luminosity scaled to the bolometric luminosity.

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.
