Left panel: comparison of the large separation for ℓ = 0 modes with the one derived by Miglio & Montalbán (2005) in their models A3, with radiative core and A4, with convective core. Right panel: comparison of the small separation with the models A3 and A4. The agreement between the data points of our study and the models is significantly better than for the small separation obtained by Bouchy & Carrier (2002) (see Miglio & Montalbán 2005)
