dc.descriptionWe present B and I band photometry, gas and star kinematics and 3D modelling of 7 giant spiral galaxies. The stellar systems studied have morphological types spanning from S0/a to Sc and absolute magnitudes from -20.6 to -22.5. The spectra have been collected with the spectrographs Boller & Chivens and EFOSC2 of the 2.2m ESO-MPI telescope. Images have been taken with the same telescope. The models fit simultaneously the photometric and kinematics data using a disk+bulge tridimensional model. The distribution of luminous matter, coming from the fit of the photometric data is compared with the distribution of total matter derived from the velocity dispersion and velocity curves. The intrinsic properties of these galaxies, such as the disk/bulge mass ratio, the total mass and the scale length of the galaxy components are presented and discussed.
