Notes.

^(a)

For definition of spectral models see text.

^(b)

Radius of the emitting area (for BB) or inner disc radius for an inclination of Θ = 0 (for DiscBB, for the definition see text).

^(c)

Observed flux in the (0.2−10.0) keV band, derived by integrating the best-fit model.

^(d)

Source intrinsic X-ray luminosity in the (0.2−10.0) keV band corrected for absorption and assuming a distance of the source of 50 kpc.
