The effect of group size on synchronization results when there is both neighbor and flow information (κ0 = 1/2) for low (a,b), moderate (c,d) and high (e,f) flow noise levels and for low (yellow online, grey in print), moderate (orange online, white in print) and high (blue online, black in print) levels of neighbor noise within each of these flow noise conditions. Length of bars represent the upper and lower quartiles.
