Figure 5. (a) Fittings of $\tfrac{{\rm{d}}\bar{{ \mathcal R }}}{{\rm{d}}g}$ at gc = 0.5 and of maximum of $\tfrac{{\rm{d}}\bar{{ \mathcal R }}}{{\rm{d}}g}$, respectively as a function of N. (b) Peak position gp minus gc as a function of N, tending to 0 with N large. Fitting models and parameters are given in the text.
