P_S/N (grey) for KIC 3733735, with the x-axis scaled in frequency (top) and in period (bottom). The p₀ probability of the pattern is shown in the top panel. The dashed horizontal orange and red lines correspond to the p_det = 0.1 and 0.05 detection thresholds computed from Eq. (6), respectively. The peaks included when computing the pattern probability p₀ are shown in darker grey. The black arrows show the period spacing between some peaks of the pattern. The mode frequencies computed for ℓ = 1, m = 0 modes with GYRE are shown for (from right to left, n = −1, −2, −3 and −4) g modes (light blue) and the n = 1 p mode (dark blue). The period spacing between consecutive g modes is shown.
