Dynamical masses (black squares), dust masses (red triangles), and black hole masses (green stars) compared to the CO(2–1)-derived molecular gas masses assuming a ULIRG α_CO, with a CMB correction (light shaded symbols) and without a CMB correction (dark shaded symbols). For the CO(2–1)-derived values, we assume that the low-J CO emission is thermalised (). Most molecular gas masses are high, spanning 0.1 − 1× the dynamical mass.
