Stretched échelle diagram of KIC 5792889 that does not show any magnetism-induced perturbation. The x-axis is the stretched periods τ modulo ΔΠ₁ ≈ 81.6 s. The peaks with S/N > 10 are shown by the grey points (l = 0 and l = 2 modes have been removed). The green ‘+’ stands for the m = 1 modes. The red ‘−’ stands for the m = −1 modes. The blue ‘•’ shows the m = 0 modes. The best-fitting results are plotted by the cross.
