Top panel: rotation profiles as a function of the normalized mass m/M_⋆ for 1.3 M_⊙ MS models #6 (magenta), #7 (blue), #9 (red), #10 (green) and #11 (black) shown in Fig. 4. Second panel: rotational splittings for ℓ = 1 modes as a function of the normalized frequency ν/Δν for models #7, #9, #10 and #11 (same colors as above). Third panel: β_nℓ for the same models. Bottom panel:  ⟨ Ω ⟩  = δν_nℓ/β_nℓ for the same models. The large separation Δν goes from 97.6 μHz (model #7) to 63.2 μHz (model #11).
