Notes. rin is the inner disc radius at which the reflection component is located (in units of rg) and relrefl the reflection fraction. The inclination has been fixed to 65° both for the kdblur and rfxconv components and the ionisation parameter to log (ξ) = 4 for the rfxconv component. In addition, the power law emissivity index has been fixed to 3 and the outer radius to 400 rg for the kdblur component (see text). The flux has been calculated both including (Ftot) and excluding (Fdisc) the reflection component.
