Ratio of the recovered (OUT) to injected (IN) geometric parameters for the simulated sources detected with FQ = 1 and 2: θ (top), position angle (middle) and ellipticity (bottom). The ratio is given as a function of the detection S/N estimated from the cold residual maps. The light and dark grey shaded regions (denoted by the dot-dashed and long-dashed lines, respectively) highlight the behaviour of 95% and 68% of the sources, respectively, in each S/N bin. The median of the ratio distributions are shown with a solid line. The 0%, 10% and 50% levels of uncertainty are overlaid using a red solid, dashed and dotted line, respectively.
