The line energy is given in the rest frame of the source. The normalizations $K_{\rm pwlw}$ and $K_{\rm bb}$ correspond to the \pn\ spectrum. $E_{\rm rest}$, $\sigma$ and $kT$ in keV, $K_{\rm pwlw}$ in $10^{-4}$~ph~~keV$^{-1}$~cm$^{-2}$~s$^{-1}$ at 1~keV, $K_{\rm line}$ in $10^{-5}$~ph~cm$^{-2}$~s$^{-1}$, and $K_{\rm bb}$ in units of $10^{-5}$~$L_{39}/D_{10}^{2}$ where $L_{39}$ is the source luminosity in units of $10^{39}$ erg~s$^{-1}$ and $D_{10}$ is the distance to the source in units of 10~kpc.
