Notes:
Model applied in XSPEC notations: CONSTANT* WABS*( EZDISKBB+ GAUSSIAN+ POWERLAW) with $N_{\rm H}$ fixed to 5.4 $\times$ 10²¹ cm^-2. Errors are given at the 90% confidence level ( $\Delta \chi^2=2.7$ ).
^a Disc normalization K is proportional to $(R/D)^{2}\cos\theta$ , where R is the inner disc radius in km, D is the distance to the source in kpc and $\theta$ the inclination angle of the disc.
^b Computed in the 2-20 keV range.
^c Extrapolated in the 0.001 keV-10 MeV range.
^d Based on the RXTE/PCA light curve.
