Correlations between observed properties (input values) and the recovered values (model). From left to right, we show log L/L_⊙, T_eff, and Π₀. Notably, outliers in one panel are not necessarily outliers in other panels. To show this property, we highlight the three most outlying points (the difference divided by the measurement uncertainty) in each panel with colour and indicate the same stars with coloured outlines in the other two panels. Outliers in luminosity are shown in orange, outliers in effective temperature in blue, and outliers in Π₀ in green. The shift towards intermediate Π₀ is discussed in the main text.
