Mode inertia for the model ℳ, depicting the modes from a full model (transparent points) and truncated scanning method (opaque points) calculation, abbreviated FMC and TSM, respectively. All plotted points are connected by a solid grey line to guide the eye. The inertia valleys containing observable p-mode-like oscillations for both the dipole (red) and quadrupole (blue) modes are recovered. The lowest-order dipole mode has been removed from consideration, as can be clearly seen at ν ≈ 20 μHz. Note that the recovered radial modes are identical for an FMC and TSM calculation.
