Table 4

Model for the Fe-K emission line region.

Parameter value
Γ a 1.924 ± 0.010
R b 0.64 ± 0.11
q c −2.23 ± 0.20
cosi d 0.95 (> 0.944)
F refl e 3.9 ph m-2 s-1
F line f 0.09 ± 0.03 ph m-2 s-1
σ line g < 2900 km s-1

Notes.

(a)

Photon index of the primary continuum.

(b)

Scale R for reflection. For an isotropic source above an infinite disc R = 1. This value corresponds to seeing equal contributions from the reflected and direct spectra.

(c)

Slope of the emissivity ϵ of the disc, power-law ϵ ~ rq.

(d)

Cosine of inclination angle i of the line of sight to the disc. The fit reached the maximum (hard) value of the model.

(e)

Total flux of the reflection component. Not a free parameter but derived from the fit.

(f)

Flux of the narrow emission line at 6.40 keV (energy fixed).

(g)

Gaussian width of the narrow emission line. We find an upper limit. For practical purposes, we keep its value to 2000 km s-1.
