Upper panel: Dipole (ℓ = 1) average of the computed period spacings, , assessed in a range of periods that includes the periods observed in EC 04207, shown as curves of different colors according to the different stellar masses. We consider the effective temperature T_eff = 27 288 ± 545 K (Voss et al. 2007). Lower panel: Same as in upper panel, but for quadrupole (ℓ = 2) modes. The red circles correspond to different possible period spacings as predicted by the statistical tests (see Fig. 22).
