Notes. Uncertainties are reported at 90% confidence level. The spectral parameters are defined as in XSPEC. The units of the line normalisations are in photons/cm2 s−1. Fbb and FCompt represent the unabsorbed fluxes in the (0.1–100) keV energy range associated with the accretion disc and the Comptonisation component, respectively.
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.
