X-ray spectral models for the 2007 Chandra data.

Model NH Normalization Γ or kT C/d.o.f.

PL 3 65/524
BB 3 65/524

Notes. The errors correspond to 68% confidence intervals. NH is kept frozen during the fit and is given in units of 1020 cm-2. The power-law normalization is in units of 10-6 erg cm-2 s-1 at 1 keV.

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.
