Comparison of the flux density and FWHM between fitting results and input models. The left, middle, and right panels show the results for sources detected at S/N = 4.4–5.5, S/N = 6.5–7.8 and S/N ≥ 12.3, respectively. Different colors indicate different visibilities used in the simulation, corresponding to the different array configurations. White circles and error bars show 50 ± 34% percentiles in the bins of output values. Black solid and dashed lines correspond to the averages and standard deviations of the fitting results and output models, which are also shown in the bottom right of each panel.
