From: Landau damping effects in the synchronization of conformist and contrarian oscillators

Characterization of synchronization in Eq. (1) as the coupling strength increases.
The FD is fixed as Δ = 0.5 and γ = 0.5. (a) The order parameter r vs the coupling strength κ. Letters A, B, C denotes the three conditions that will be analyzed in the next Figure. (b) Given fixed central frequency of FD Δ = 0.5, the critical values of vs the width of FD γ.
