Left: the fraction of systems that would be detectable with Spitzer (with F/F_star(70   μm) ≥ 0.55 after 1 Gyr of collisional and dynamical evolution) as a function of the eccentricity of the innermost giant planet e_g for the mixed and combined seeds simulations. The error bars are based on binomial statistics  (see Burgasser et al. 2003). This essentially represents a horizontal slice through the top left panel of Fig 8. Right: the fraction of systems with 0.5   M_⊕ or more in surviving terrestrial planets as a function of F/F_star(70   μm) ≥ 0.55 (1 Gyr) for the mixed and seeds simulations. Systems with F/F_star < 10^-2 are included in the bin at F/F_star ≈ 10^-2. The Spitzer detection limit is shown as the dashed line. This represents a vertical slice through the bottom right panel of Fig. 8.
