The square of the empirical distribution function |C|^2 from 10,000 samples of the ‘transition distribution’ discussed in Section 3.2 (and shown in Fig. 4), for |C|^2 > C_min. There are two color schemes present in this figure. The predominantly dark, multicolored colored ‘X-shaped’ region in the center corresponds to values of |C|^2 for the first contiguous hypervolume (the area containing the origin); the colorbar at right applies to colors in this region. The lightly-colored, monotone areas away from the first contiguous hypervolume correspond to additional contiguous hypervolumes (areas) with C|^2 > C_min source. The colors of these areas are arbitrary and only serve to visually differentiate nearby contiguous areas from one another.
