Échelle diagram of the frequencies of the best models from test 2 (top row) and 3 (bottom row) including the ratios. The left columns show frequencies from scenario A, while the right columns show frequencies from scenario B. Circles represent modes ℓ = 0, triangles represent modes ℓ = 1, and diamonds represent modes with ℓ = 2. The black symbols with error bars indicate the observed frequencies and green symbols represent the model frequencies. The dotted gray line indicates the 56 μHZ frequency.
