We apply the stellar population synthesis code by Cid Fernandes et al. to model the stellar contribution for a sample of 209 type II AGNs at $0.3$ is $1.24\pm0.76$ for the core [O III] line and $1.20\pm0.96$ for the [O II] line, which suggests that $\sigma_{g}$ of the core [O III] and [O II] lines can trace $\sigma_{*}^c$ within about 0.1 dex in the logarithm of $\sigma_{*}^c$. For the secondary driver, we find that the deviation of $\sigma_{g}$ from $\sigma_{*}^c$ is correlated with the Eddington ratio.
