(\cite{all96}), \mbox{Verdes-Montenegro} et~al. (\cite{ver98}) and Gallagher et~al. (\cite{gal08}). The indicator ``Central Activity'' was taken from: Shimada et~al. (\cite{shi00}), \mbox{de Carvalho} et~al. (\cite{dec97}), Coziol et~al. (\cite{coz98a}, \cite{coz00}) and Xu et~al. (\cite{xu03}). \\ $^b$ The disagreement between optical and kinematic position angle could be associated with the presence of a bar. \\ $^c$ From Plana et~al. (\cite{pla03}). \vspace*{2mm} \end{table}
