Abstract:
We present the kinematical data obtained for a sample of active
(Seyfert) and non active isolated spiral galaxies, based on long slit
spectra along several position angles in the Hα line region and,
in some cases, in the Ca triplet region as well. Gas velocity
distributions are presented, together with a simple circular rotation
model that allows us to determine the kinematical major axes. Stellar
velocity distributions are also shown.
