Dynamical mass, derived from the width of the Hα emission line versus the baryonic mass (stars+gas), derived from the spectral fit. The two diagrams display the results emerging from two different assumptions about the kinematics of the Hα emitting gas. In the spherical case it is assumed that virial motions take place in a spherically symmetric structure and in the disc case it is assumed that the gas clouds move in circular orbits in a disk. Overplotted circles are the median values after binning along the x-axis. The hatched line marks the 1:1 relation.
