Replicated échelle diagram of model ℳ obtained after application of the truncated scanning method to calculate red-giant oscillations. The orange diamonds, red upwards and blue downwards triangles depict the l = 0, l = 1 and l = 2 modes, respectively. A scaling in size related to the inverse of its inertia is applied to each plotted mode. The observable mixed-mode regions surrounding the acoustic resonances have been calculated and plotted for the dipole and quadrupole modes. For contrast to the initial situation, compare to Fig. 4.
