Spatial domains populated uniformly at random.

<p>Average values (markers) of the three metrics, with the standard error of the mean, from a sample of 10 domains populated uniformly at random. Circular domains <i>ρ</i> = 0.1, <i>R</i> = 150. Annulus domains <i>ρ</i>_<i>A</i> = 0.1, <i>R_A</i> = 0.75, <i>ρ</i> = 0.076, <i>R</i> = 150. (a) Typical circular domain. (e) Typical annulus domain. (b) and (f) Average radial metric with <i>L</i> = 30 for the circular and annulus domains, respectively. (c) and (g) Average angular metric with <i>M</i> = 30 for the circular and annulus domains, respectively. (d) and (h) Average angular pair-correlation metric with <i>N</i> = 30 for the circular and annulus domains, respectively. In the calculation of the average angular pair-correlation metric <i>n_s</i> = 100 occupied sites were selected at random from each domain in the sample.
