Growth vectors in the photometric plane of the bulges (which relates the three bulge parameters: n, μ_eff, and r_eff) driven by our merger experiments, compared to the observational distributions of S0s and spirals by L10. The dashed and dotted-dashed arrows indicate the trends observed by L10 for bright (M_K(bulge) < −22.7 mag) and faint bulges (M_K(bulge) > −22.7 mag) of the S0s in the NIRS0S survey. The solid arrow marks the trend found in our models. Consult the legend for the observational data in the figure. The legend for the models is the same as in Fig. 1.
