Acoustic power vs. Δν for , n = 12 and m = 0 (red), ±1 (violet), and ± 2 (blue) at an inclination angle i = 80°, for QS (ϵ = 0, upper panel) and for a spot located at a depth of 0.98 R_⊙ and with ϵ = 0.01 (second upper panel), 0.4 (third upper panel), and 1.0 (bottom panel). The black dashed lines represent the spectra resulting from the sum of all the m components. Because of the initial conditions in Eq. (10), the observed acoustic power in the | m | > 0 modes is twice the power that would be observed in the case of stochastic excitation.
