Fraction of final solid mass content in planets in a system divided by the initial solid mass in the planetesimal disk. The light green line corresponds to the population around a 0.1 M_⊙ star with 50 embryos (NGM10) and the dashed, dark blue line to the population around a 1.0 M_⊙ star with 100 initial embryos (NG76). The dotted histogram shows the same quantity for the systems with at least one existing giant planet (M > 100 M_⊕) in NG76.
