Heatmap representation of the fractional differences Δf = f_data2 − f_data1 between the two datasets, for each stellar mass bin and classification scheme. Each panel shows the comparison as a function of environment (x-axis) and physical process (y-axis). Red cells denote higher fractions in data2 relative to data1, while blue cells indicate lower fractions. The color intensity reflects the amplitude of the difference, with neutral tones corresponding to consistent results within uncertainties.
