KS test results for metallicity analysis with λ = 3 for high-mass planets. The bottom-left triangle represents the test results for planetary mass, while the top-right triangle represents the results for orbital radius. The two-sample KS statistic d and the corresponding probability p are shown for each metallicity sample pair. Grids with p-values less than 0.05 for orbital radius are highlighted in red, and those for planetary masses are highlighted in cyan.
