Average masses of the largest 〈M₁〉 (filled circles) and second-largest 〈M₂〉 (open circles) planets against the corresponding initial disk masses (IDM) for the two central star masses 0.6 M_⊙ (in green, the top plot) and 0.8 M_⊙ (in blue, the bottom plot), and the empirical fits for 〈M₁〉 (solid line) and 〈M₂〉 (dotted line). Since the systems starting with 5 M_⊕ typically contain only one planet, they are not included in the plots.
