Synthetic populations of planets calculated in single-embryo mode with reduced type I migration (f_I : 0.1) as a function of a and M. The mass fraction of the summed-up ices is shown in color. The top panel shows the population of planets with a nominal planetesimal surface density slope β_pls, whereas the other two panels have steeper planetesimal surface density slopes as indicated in the top left of the panel. The bottompanel displays the population of planets, where embryos and planetesimals are only placed outside of 0.6 au.
