Table 3: The parameters of the disk: $z_{\rm l}$ is the shift and $W_{\rm l}=\sqrt {2}\sigma $ is the Gaussian broadening term from the disk which is a measure of the random velocity in the disk, $R_{\rm inn}$ is the inner radius, $R_{\rm out}$ is the outer radius. $z_{\rm G}$ and $W_{\rm G}$ represent the parameters of the Gaussian component.
