Deviations, for the actual observations considered in Sect. 4, of DBNets mass estimates (M_p) from the literature values (M_B) reported in Bae et al. (2023), as a function of the resolution of the images. Note that all the observations in the shaded area have been additionally convolved with an appropriate Gaussian beam to match the resolution of the training data (0.12a, black dashed line) as explained in Sect. 4.
