Projections of the C09 and R10 oscillations (green dots) and the K3 and K100 evolutionary paths during the two stages of planet formation/migration on the (e₁,e₂)-plane. The first stage of accretion includes the passage through the 2/1 MMR and the capture into the 3/2 MMR (blue points). The evolution during the second stage of the runaway mass growth and the type II migration is shown as black dots for the K3 solution and as red dots for the K100 solution. The ACR-families are shown by continuous lines; one is parameterized by m₂/m₁ = 1, the other by m₂/m₁ = 3.51. The black cross shows the initial configuration of the planet pair.
