From: Interplay of coupling and common noise at the transition to synchrony in oscillator populations

Values of 〈J〉 according to (15) for different γ/σ2 as functions of μ/σ2.
From top to bottom: γ/σ2 = 10−4, 10−3, 10−2, 10−1, 1. Brown dashed line corresponds to the system of identical oscillators γ = 0. Vertical grey line shows the border of stability of the fully synchronous state for γ = 0.
