Figure 3.

(A) is a sketch showing the distribution of A produced by a spot of $n_1$ surrounded by the sea of $n_2$. (B and C) show the width of an isolated spot of $n_1$ as a function of $D_A$ (B) and ${\gamma }_1$ (C). The curves show the results from theory, and the symbols are from simulations. Parameters are $\delta =0.01$, ${\delta }_A=0.02$, and ${\gamma }_A=0.04$. $\kappa =0.06$ in (B), and $D_A=800$ in (C). To see this figure in color, go online.
