Relative amplitude (in logarithmic scale) of g-mode oscillations as a function of the inclination angle and the degree ℓ (assuming that m = 0). The values ℓ = 1 (black), 2 (red), 3 (cyan), and 4 (blue) are represented. These visibility functions are evaluated for a star with parameters representative of KIC02697388 and in the Kepler band-pass.
