Notes. Fitted models are of the form wabs × phabs × (apec+apec). The absorptions are fixed to 1.15 and 0.29 × 1022 cm-2. In the first case, the first temperature is fixed to 0.617 keV, whereas in the second case, both temperatures are fixed (cooler component at 0.617 and hotter component at 1.89 keV). Fluxes refer to the 0.5–10.0 keV band, except for ROSAT data where they are given in the 0.5–2.0 keV band.
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.
