Distributions of SFH parameters t0 (top row) and τ/t0 (bottom row), shown from left to right. Grey histograms represent the distribution of all the galaxies in the cluster in all panels. Red, blue, and black histograms represent the distribution of red, blue and all galaxies at different cluster-centric distances: all the galaxies in the cluster (first column), galaxies within 0.5R₂₀₀ (second column), and galaxies within 0.5R₂₀₀ and R₂₀₀ (third column).
