Upper panel: dipole (ℓ = 1) average of the computed period spacings, , assessed in a range of periods that includes the periods observed in the GW Vir star TIC 095332541 and TIC 333432673, shown as black (blue) curves corresponding to stages before (after) the maximum T_eff for different stellar masses. The location of TIC 333432673 when we use the spectroscopic effective temperature, T_eff = 120 000 ± 10 000 K, and the dipole period spacing ΔΠ_ℓ = 1 = 20.19 s, is highlighted with a red circle in the upper panel. Lower panel: same as in upper panel, but for the average of the computed period spacings with ℓ = 2. The GW Vir star TIC 09533254 is drawn in this plot considering a quadrupole period spacing of ∼13 s (see Sect. 5.5).
