Model $\mathcal{B}$ is similar to model $\mathcal{A}$ with one absorbing component and model $\mathcal{C}$ to model $\mathcal{B}$ with another absorbing component and a few Gaussian emission lines (see their parameters in Table 7). Both $\mathcal{B}$ and $\mathcal{C}$ models include the Galactic absorption (with fixed $N_{\rm H}=4.67\times 10^{20}$ cm^-2) and the Fe-K $\alpha$ line (with its parameters fixed to the model $\mathcal{A}$ values). Normalizations $K_{\rm pwlw}$ and $K_{\rm bb}$ correspond to the EPIC-pn spectrum. $K_{\rm pwlw}$ in units of 10^-4 ph keV^-1 cm^-2 s^-1; kT in keV; $K_{\rm bb}$ in 10^-5 L₃₉/D₁₀² where L₃₉ is the source luminosity in units of 10³⁹ erg s^-1 and D₁₀ is the distance to the source in units of 10 kpc. $N_{\rm H}$ is given in cm^-2. Velocities, given in km s^-1, are relative to the systemic velocity of UGC 11763. Errors quoted are at 90% confidence level.
