Quantities f_T and φ_T in two non-rotating models with masses 1.8 M_⊙ and 2.0 M_⊙. The two models have virtually the same temperature (8143.9 K and 8137.3 K, respectively), but different log  (g) values (4.1249 dex and 3.9593 dex, respectively). The different line styles correspond to different ℓ values, and the overlapping vertical dotted lines (which are hard to distinguish) indicate the position of the fundamental modes of both models.
