Power density spectra of three CoRoT targets (ID given on the right side), with shaded regions of these bar code spectra that reproduce the universal red-giant oscillation pattern and identify the location of the different harmonic degrees; the denser the background, the higher the probability of having the short-lived p mode realized there. Black dashes in the ℓ = 1 ridges indicate the asymptotic spacing of the mixed modes as derived from Eq. (2). They do not give their exact eigenfrequencies, since the asymptotic relation does not account for the mode bumping of mixed modes.
