Same dependences as in Fig. 10 but computed for nine pairs of spot decay rates andratios between facular and spot lifetimes. For each pair of these parameters, calculations are performed for five realizations of active regions emergences. Shown are calculations with T_fac ∕T_spot = 2 (black), T_fac∕T_spot = 3 (blue), and T_fac∕T_spot = 5 (red). For each T_fac∕T_spot ratio, we perform calculations with three values of spot decay rates: 41, 25, and 10 MSH day⁻¹.
