Growth maps for four values of Ṁ3, the mass-accretion rate after 3 Myr, with fixed pebble-to-gas flux ratio ξ = 0.02. The initial accretion rate is 10−7 M⊙ yr−1 in all models. Increasing the steepness of the temporal accretion rate profile, obtained here by lowering the initial disc size, decreases the region for forming gas-giant planets.
