NSC stellar mass function for the models listed in Table 1 compared to the observed NSC mass function derived from the $M_{\text{NSC\hspace{0.17em}}}^{\text{stellar\hspace{0.17em}}}-M_{\text{galaxy\hspace{0.17em}}}^{\text{stellar\hspace{0.17em}}}$ correlation. The orange region is the observed NSC mass function derived from the galaxy stellar mass function of Baldry et al. (2012), while the magenta line is the NSC mass function derived from the galaxy stellar mass function for model A1; both are denoted with an asterisk in the legend. The error in simulations is estimated as ${\mathrm{\Phi }}_{\text{NSC}}/\sqrt{N}$, where N is the number of NSCs in the bin.
