## Figure 3.
(a) The 8^{th}bin in Figure
2
(b) contains two differentX_{2}values corresponding to the “blue” instances in Figure
2
(a) forX_{1}~1.26. The corresponding values of X_{2} and –S_{2}, obtained from the plot of X_{2} versus –S_{2}, are (1.54, -1.35) and (2.93, 0.93). These two points are considered a pair and linked
with a red line. (b) The 5^{th} bin of Figure 2(b), corresponding to the “red” instances in Figure 2(a), contains four instances of X_{1} ~0.26. Their corresponding values of X_{2} and –S_{2} are (1.20, 0.05), (1.37, 0.35), (1.66, 1.02), and (1.99, 1.65). Two points each are
considered a pair and linked with a red line.
