a, Susceptibility computed for six different system sizes LWϵ [25, 50, 100, 200, 400, 800] and for different values of the neighbor coupling parameter θ. b, Value of the susceptibility in three different regimes: i) θ = θc, ii) θ < θc and iii) θ > θc, where θc is the value of the neighbor coupling parameter θ where the susceptibility reaches its maximum value. c, Width of the susceptibility peak \({\mathcal{W}}\) - as defined in equation (18) - for different system sizes L.
