Fig. 2.

Test 2 Time evolution of the initial distribution given in Fig. 2a in the four settings 1-4. The sensing radius of the cells is $R=0.5$ and $\mathcal{S}$ is (72) with $m_{\mathcal{S}}=10,{\sigma }_{\mathcal{S}}^2=0.05$ and $(x_{\mathcal{S}},y_{\mathcal{S}})=(4,4)$. Setting 1 is represented in Figs. (c–f): local q and non-local $\mathcal{S}$, ${\gamma }_{\mathcal{S}}={\delta }_R(\lambda )$. Setting 2 is represented in Figs. (g–j): non-local q and $\mathcal{S}$ with sensing functions ${\gamma }_q={\gamma }_{\mathcal{S}}={\delta }_R(\lambda )$. Setting 3 is represented in Figs. (k–n): non-local q and $\mathcal{S}$, independent sensing with ${\gamma }_q={\gamma }_{\mathcal{S}}=H(R-\lambda )$. Setting 4 is represented in Figs. (o–r): non-local q and $\mathcal{S}$, dependent sensing with $\gamma =H(R-\lambda )$ (color figure online)
