Notes.All uncertainties are given for Δχ² = 1 corresponding to a 1σ confidence for one degree of freedom.

^(a)

For model definition see text.

^(b)

Normalisation of the thermal model component: radius (BB), inner disc radius for inclination of Θ = 0 (DiskBB), and emission measure (APEC).

^(c)

Observed flux in the (0.2−10.0) keV band.

^(d)

Unabsorbed luminosity in the (0.2−10.0) keV band. A source distance of 60 kpc is assumed.
