Typical cumulative histograms and the shaded area in each subplot is the AUC. The normalized AUC is obtained by dividing the shaded area by the total area of the rectangular box. In these plots, the x-axis indicates the angular value and y-axis indicates the cumulative number of data points. Fractional AUCs are calculated and referred to as AUC(<δ), indicating the area under the curve from angular deviation = 0 to angular deviation = δ. For example, the AUC, AUC(<10), and AUC(<20) are shown in a, b, and c
