Distribution of Monte Carlo variables for original sample from Emsenhuber et al. (2021b), and effect on number of giant planets for the M_* = 1 and N_Embryos = 50 model run. The colour marks the number of planets in the system after 20 Myr of evolution. Shown are the correlation between the gas mass, M_g, metallicity, [Fe/H], inner protoplanetary disc radius, r_in, and external photo-evaporation rate, ${\dot{M}}_{\text{wind }}$.
