Deconvolved source sizes as a function of total flux density. Unresolved source (as defined by Eq. (7)) have deconvolved sizes set to 0. The red circles indicate the median deconvolved sizes in bins of S_T with 1σ error indicated by the gray bars. The red dashed line is the maximum deconvolved size (Θ_max, Eq. (8)), the green dash-dotted line is the median size relation (Θ_med) derived from Eqs. (11) and (12), and the solid black line is the minimum deconvolved size (Θ_min, Eq. (9)).
