Table B.2.

ALMA rest-frame 260 μm (observed-frame 870 μm) flux densities (F) and effective radii (R_e), obtained through the fit on the visibilities using python, assuming different symmetric (i.e. axis ratio = 1) models. The model with the smallest BIC (Bayesian Information Criterion) value is the preferred model. The stars (^⋆) mark the targets with the peak S/N < 8 in the ALMA maps, for which we do not consider the size measurements to be reliable. For point sources, we tabulate only the results of the point source model. For extended sources, we do not tabulate the result of the fit with point source model, since it gives a poor fit to the data and underestimate the fluxes. ^aFor the Gaussian+point model, we report: the total flux F(tot) = F(point)+F(Gaussian), the flux of the point source F(point), the half-light radius of the total profile R_e(tot), the half-light radius of the Gaussian component R_e(Gauss). ^bFor XID36 and cid_451, the difference in BIC between the exponential and Gaussian model is < 2, therefore it is not clear than one model is performing better than the other.
