Table 6: Parameters of the models maximizing the KS statistics for the 2D distribution of TNO colors, and corresponding d and p. x1, y1 and x2, y2 refer to the coordinates of the blob centers in case of bimodal models, and to the ends of the segment in case of a continuous model. $\sigma _x$ and $\sigma _y$ are the widths of the spread in xand y. f is the fraction of the population in blob 1.
