Table 4:

Parameters for the very broad component of the Fe K $\alpha$ line in a two-components model.
		Gauss¹	Laor²
E	keV	$6.41\pm0.01$	$6.47\pm0.03$
FWHM	eV	$0.29\pm0.04$	$\dots$
Lum	10⁴¹ erg s^-1	$4.64\pm0.16$	$5.0\pm0.7$
q		$\dots$	$1.5\pm0.5$
i	deg	$\dots$	$15\pm7$
$\chi^2/\nu$		339/240	334/239

Notes. Third column: one Gaussian with free width. Fourth column: profile including relativistic effects. The reduced $\chi^2$ refers to an intermediate fit (see Sect. 2.2). ⁽¹⁾ We list the energy of the centroid, the luminosity of the line and the FWHM.⁽²⁾ We list the energy of the centroid, the luminosity of the line, the emissivity law, q and the inclination angle, i.
