Comparison between the mass estimates inferred from CO (MH2, CO), [C I] (MH2, [CI]), [C II] (MH2, [CII]) and dust continuum (MH2, dust), as described in the text. The one–to–one relation is shown as a dashed line. The different estimators lead to generally consistent results overall, with MH2 = 1010−11 M⊙, although different estimators lead to a different spread of values within our sample. The [C II]–based estimates are systematically higher than the ones based on other tracers. The arrows highlight how the data points would move if some parameters would change from their fiducial values to others commonly used in the literature.
