Notes. The first column shows the determined emission component. Hβ1, Hβ2, and Hβ3 and Hγ1, Hγ2, and Hγ3 are the determined three Gaussian components in Hβ and in Hγ, and Hα1, Hα2, Hα3, and Hα4 are the determined four Gaussian components in Hα (three broad components plus one probable narrow component). The second, third and fourth column show the determined central wavelength in units of Å, the second moment in units of km/s, and the emission flux in units of 10−17 erg/s/cm2. For the optical Fe II emission, the shifted velocity and the broadened velocity in units of km/s are listed in the second and third column, and the total flux is listed in the fourth column. The second part of the table lists the model parameters for the elliptical accretion disk model applied to describe the asymmetric broad Hβ, as shown in Fig. 8.
