Figure 3.

Minimal values 〈R1〉opt of the time-averaged first order parameter 〈R1〉 of the phase ensemble (Equation 1) controlled by continuous CR stimulation vs. the number of stimulation sites Ns for different values of the parameter σ in Equation (3) as indicated in the legend. The stimulation strength I was varied in the interval [0, 60], i.e., Imax = 60. Other parameters as in Figure 2.
