Appendix 1—figure 4. Chemotaxis of a rigid cluster.

(a) ${\tau }_p=5$. (b) ${\mu }_p=0.5$. In both cases $N=50$ cells with $\gamma =6$ are placed on the right of the field and move towards higher concentration of the gradient (the semicircle indicates the resource location, where the gradient is highest. All other parameters as in main text).
