Comparison between our various photometric methods described in Sect. 3.2 for S/N >  5 sources. The blue dots are our measurements and the red line is the one-to-one relation. Upper left, upper right, and lower left panels: comparison between the 2D-fit flux density (x-axis) and the aperture, 2σ-clipped, and peak flux densities, respectively. Lower right panel: ratio between the peak flux and the 2D-fit flux as a function of the ratio between the source area (convolved by the synthesized beam) and the synthesized beam area. The dashed line indicates the expected trend (see Sect. 3.5).
