Description
We present a comparison between ionized gas and stellar kinematics for a
sample of 5 early-to-intermediate disk galaxies. We measured the major
axis V and velocity dispersion radial profiles for both gas and stars,
and the h_3 and h_4 radial profiles of the stars. We also derived from
the R-band surface photometry of each galaxy the light contribution of
their bulges and disks. In order to investigate the differences in the
velocity fields of our sample galaxies we adopted the self-consistent
dynamical model by Pignatelli & Galletta (1998), which takes into
account the asymmetric drift effects, the projection effects along the
line-of-sight and the non-Gaussian shape of the line profiles due to the
presence of different components with distinct dynamical behavior.
