Left panel: ratio between remodelled and previous literature estimates of dynamical masses of UCDs is plotted vs. their remodelled mass. The original literature source is indicated by the colour coding of the circles around the data points. See Sect. 2.3 for details on the colour coding. For all the data points, we have recalculated the dynamical mass in this paper. Small dots (without a circle) indicate the ratio between the remodelled and literature dynamical mass-to-light ratio M/L_dyn. Right panel: ratio between remodelled and literature mass, cleaned of the effect of update in distance modulus, and without the CenA sample of Taylor et al. (2010), is plotted vs. the literature mass estimate.
