ROC curves for galaxies at different redshift bins, colour-coded as shown in the legend, with each label also listing the corresponding AUC score and the number of galaxies in the bin N. Top Plot (a) shows the ROC curves for different redshift bins within the low redshift range z = [0.01, 0.1] and the bottom plot (b) shows the ROC curves for different redshift bins within the high redshift range z = [0.1, 0.2], along with the ROC curve for the complete low redshift range z = [0.01, 0.1] shown for comparison.
