Baryonic, stellar, and gas masses (estimated using the relation between Σ_SFR and Σ_gas from Kennicutt 1998) as fractions of the dynamical mass. We find that the gas mass, and hence the baryonic mass, is approximately one order of magnitude higher than the stellar mass. Although the inclusion of the gas component reduces the large discrepancy in mass found in Fig. 7, the difference of a factor of 3 − 4 between the dynamical and baryonic mass still remains for all but one object.
