a References. - The indicator ``High IR luminosity'' was taken from the following sources: Allam et al. (1996), Verdes-Montenegro et al. (1998) and Gallagher et al. (2008). The indicator ``Central Activity'' was taken from: Shimada et al. (2000), de Carvalho et al. (1997), Coziol et al. (1998, 2000) and Xu et al. (2003).
b The disagreement between optical and kinematic position angle could be associated with the presence of a bar.
