Measured (left) and residual (right) Sérsic-derived quantities as a function of projected halo-centric distance. The coloured lines denote the linear fits to the sub-samples. The residual parameters are defined as the mass-trend subtracted parameter values. Galaxies with log₁₀(M_*/M_⊙) > 9 are also marked with a black cross. The Spearman’s ρ rank coefficient and the p-value are annotated in the subplots. We use the same y-axes range between the corresponding measured and residual quantities to highlight the reduction in scatter.
