Evolution of the total mass confined by the embryos in the INT and NON models. Red and blue shaded regions indicate the previously used embryo-planetesimal belt mass (7.35 M_⊕) and the belt mass that is three times higher (22.05 M_⊕), respectively. Colored curves represent models with different initial numbers of embryos (indicated in the key) in the range of 25–400 and with a constant 1000 planetesimals.
