Figure 6.
Frequency differences limit noise-induced synchronization. OP decreases quickly as frequency differences increase (black axis). The peak position of the phase difference density is shifted by changing frequency differences between two oscillators (grey axis). Parameters used here: a1 = 0.1, b1 = 0.32, a2 = 0.6, b2 = 0.3, τ = 1, and c = 0.8.
