We present measurements of the stellar and ionized gas velocity curves and velocity dispersion profiles along the major axis for two Sa galaxies, NGC 2179 and NGC 2775. The luminosity profiles and the stellar kinematics of each galaxy are used to compute the mass distribution of the luminous and dark matter.

Abstract
We present measurements of the stellar and ionized gas velocity curves and velocity dispersion profiles along the major axis for two Sa galaxies, NGC 2179 and NGC 2775. The luminosity profiles and the stellar kinematics of each galaxy are used to compute the mass distribution of the luminous and dark matter.
