\tablefoot {The velocity $\gamma_1$ is based on Ond\v{r}ejov data, $\gamma_2$ on Rozhen data, $\gamma_3$~on OPD~data \citep{brazilie}, and $\gamma_4$ on historical data of \cite{DAObin3}.
In~solution IV $\gamma_5$, $\gamma_6$, $\gamma_7$, and $\gamma_8$ stand for {\Halpha}, {\hei}~6678~{\AA}, {\siii}~6347~{\AA}, and {\siii}~6371~{\AA}, respectively.}
