Notes. The first part of the table presents fits with a single thermal component (Swift data only), while the second and third parts list the fitting results for two thermal components of fixed temperatures for solar abundances and for non-solar Ne and Fe abundances. Unabsorbed fluxes are only corrected for the interstellar column (8.1 × 1021 cm-2). Errors (found using the “error” command for the spectral parameters and the “flux err” command for the fluxes) correspond to 1σ; whenever errors were asymmetric, the highest value is provided here. Fluxes are expressed in the 0.5–10.0 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.
