Same as Fig. 1, but with colors indicating the total momentum flux carried by IGW generated by the convective envelope (left) and the convective core (right). Dotted lines indicate the region where the stars are fully convective (left) or have no convective core (right) so that no IGW can be generated. In the left panel the vertical dashed lines connect models where the excitation has the same value: log (Σ | ℱ_J(ω,l,m) | ) = 28, 30, 32, 34, 36, 38.
