Growth vectors in the log (r_e)-log (B/T) and log (h_D)-log (B/T) planes driven by our merger experiments, compared to the observational distributions of S0’s and spirals. The blue shaded region indicates the locations in the plane that are covered by our models just using a scaling different to the one indicated in Sect. 2. Consult the legend for the observational data in the figure. The legend for the models is the same as in Fig. 2.
