Number of planets detected by transit in synthetic observations of planetary systems produced in our N-body simulations of Model I with t_start = 0.5 Myr and S_peb = 1 (red), ModelI with t_start = 3.0 Myr and S_peb = 5 (purple), Model II with t_start = 3.0 Myr and S_peb = 5 (blue), and Model III with t_start = 0.5 Myr and S_peb = 10 (yellow). Forall cases, Rocky_peb = 0.1 cm. Solid lines show stable systems, and dashed lines show unstable systems. The black lines show the results of our synthetic observations. The densely dashed green lines show multiplicity distribution combining different real fractions of stable and unstable systems. We note that the y-axes combine linear and log scaling.
