Figures 2(a) and (b) from the reference manuscript, representing the model equations 2.1-2.3, were reproduced in COPASI 4.33.246. The values r_N = 0.17 and rho_C = 0.0251 were used in the reproduction of Fig. 2(a) and (b), different to the values quoted in Table 1 of the manuscript's Supplementary Material.
