effects of the narrow lines, the double-peaked broad component of H$\alpha$ is firstly described and fitted by the theoretical elliptical accretion disk model proposed by Eracleous et al. (1995). Here, our main objective is not to accurately determine the disk parameters through theoretical model, thus, there are no further discussions about disk parameters, which has been discussed in detail in our another paper (Zhang 2011a, Paper I). In other words, we only require that the line profiles of the double-peaked broad H$\alpha$ can be best described and be well separated from the narrow lines. In this paper, we show the best fitted results for the apparent double-peaked broad H$\alpha$ in Figure \[3c390\], and the corresponding residuals in Figure \[res\]. In Figure \[res\], we also show the best fitted results for the narrow lines of H$\alpha$ and \[N [ii]{}\]$\lambda6548,6583$Å by three standard gaussian functions with the same redshift and with line parameters ratio of \[N [ii]{}\] doublet fixed to theoretical values. Based on the results shown in Figure \[3c390\] and Figure \[res\], the double-peaked broad component of H$\alpha$ can be clearly separated from the narrow lines.

Then, the line width (second moment) and the line flux of the double-peaked broad component
