In the top panels, we show how the metrics, ⁠, and Q_dn, for submissions change as the galaxy model changes; the colour scale labels the logarithm of Q_dn. The galaxy models are: uniform bulge-to-disc ratio, each galaxy has, randomly sampled from the range [0.3, 0.95] with no offset (Uni.), a 50 per cent bulge-to-disc ratio = 0.5 with no offset (50/50.) and a 50 per cent bulge-to-disc ratio = 0.5 with a bulge-to-disc centroid offset (w/O). In the lower panels, we show the PSF size and ellipticity contributions α and β. In the bottom left-hand panel, we show the key that labels each method.
