Notes. Here we report the total column density (NH, in 1022 cm-2) inferred from the X-ray measurements, the temperature and the normalization of the APEC thermal plasma (in units of 10-18
, where ne and nH are the electron and H densities in cm-3, and D the distance to the source in cm), the flux of the Fe Kα line (in units of 10-6 photons/cm-2/s), the normalization of the powerlaw component (10-5 photons/keV/cm-2/s at 1 keV), the EW of the Fe-Kα line (in keV) with respect to the powerlaw component, the upper limit to the optical depth of the Fe-K edge, and the C-stat values for the best fit model (the degrees of freedom are 2119 for the regions N, S and SN, 397 for the region DX).
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.
