Fractions of binaries per unit q measured in five mass-ratio intervals as a function of q for all the simulated GCs. To compare the q distribution in simulated clusters with different fraction of binaries, we divided ν_bin by two times the fraction of binaries with q > 0.5. For clarity, black points have been randomly scattered around the corresponding q value. The means normalized binary fractions in each mass-ratio bin are represented by red points with error bars, while the gray line is the best fitting line, whose slope is quoted in the inset.
