Example of a fit chunk for KIC 12008916  derived by Diamonds. The PSD is shown in black, while the resulting fit using the parameters listed in Tables B.37 and B.38 is indicated by a green solid line. The level of eight times the background is shown with a blue dashed line as a reference for the peak significance. The colored vertical bands highlight the oscillation modes modeled by a Lorentzian profile, Eq. (5), with ℓ = 0 in blue, ℓ = 2 in green, ℓ = 3 in orange, and ℓ = 1 mixed modes in red. The vertical dotted lines mark the central frequency ν₀ for each of the fit modes, with the corresponding mode identification (Peak #, ℓ, m) also labeled, according to the description given in Appendix B. The case of the unresolved mixed mode (26,1, −1) is shown in red because the peak has a detection probability (p_B = 0.002) below the threshold suggested in Sect. 2.3.
