Deviation from Hill-curve. Mean deviation from reference Hill-curve and Hill-coefficient of stimulus response curves for varying ${\text{r}}_{\text{k}}=\frac{{\text{k}}_{\text{cde}}}{{\text{k}}_{\text{cie}}}$. Here, k_cde = 1.0 and k_cie was varied between 0.01 (r_k = 100) and 0.6 (r_k = 1.67). All other parameter and initial values were as in Fig. 3C.
