TPR (solid lines) and CR (dashed lines) as a function of the probability computed by our membership method (Sect. 2), in bins of Galactic latitude b (top) and G magnitude (bottom). The crosses indicate the optimum probability thresholds that maximise the accuracy of the classifier (i.e. the fraction of correct classifications) at each bin, and are those detailed in Table A.1. The black line indicates the global performance and the shaded regions depict the standard deviation of the ten synthetic simulations.
