Abstract
We analyze and compare global line-profiles of 39 disk galaxies with Hi and Hii data. We find good agreement between the first and second moments of the profiles and recession and rotation velocities, respectively. The shapes of Hi and Hii profiles differ markedly, however, as the line profile asymmetries are not . Asymmetry in neither Hi nor Hii profiles is correlated with rotation curve asymmetry which suggests that differing distributions of gas, and not kinematic asymmetries, dominate the global profile asymmetries of normal disk galaxies.
