Comparison between plane and single power law models. Top: scatter with respect to the star-forming 2D plane (solid) and rKS (dashed) determined for each galactic environment, at the different spatial scales probed. Bottom: difference of the LOO score measured for the plane and the rKS models, where a > 0 indicates a preference for the plane model. The error bars are the 3σ standard errors. The black horizontal line at 0 marks where there would be no preference between the models. The plane model is preferred over the rKS at all spatial scales, increasingly so at finer spatial scales.
