Oscillation spectrum of KIC 7955301. Top panel: power spectral density of the time series after eclipse removal and filling. The dashed red line represents the stellar background noise: it is the sum of the dashed blue lines (correlated noise Harvey profiles) and the dashed green line (white noise). The solid red line represents the fit of the power spectrum, including the stellar background and the Gaussian envelope of the oscillations. Bottom panel: échelle diagram associated with the frequency spacing Δν = 10.48 μHz. The colored lines indicate the oscillation universal pattern, where blue is l = 0, green l = 1, and red l = 2. Modes of degree l = 3 are visible half way in between the l = 0 and l = 1 ridges. The horizontal dashed line indicates the location of ν_max.
