Residuals of properties compared to the medians of the posterior distributions obtained with the τ-delayed model, for log₁₀(M_*/M_⊙), the log₁₀(age/yr), referring to the mass-weighted age, and A_V [mag]. We split the simulated test sample in bins of mean S/N in the filters F277W, F356W, and F444W, 1−5 (left), 5−10 (middle) and > 10 (right). We colour-coded each simulation with the standard deviation of the posterior distribution for the three properties and included dashed and dotted lines corresponding to the average one and two standard deviations of the posterior distributions respectively. We also plotted kernel density distribution contours with black solid lines for clarity.
