Frequency Spectra for the (a) long wavelength tearing mode with kyρi = 0.05 and (b) short wavelength ITG modes with kyρi = 0.5. The background color indicates the frequency spectral density of the potential near the resonant surface φ(x0) . The frequencies of the eigenmodes for the initial profiles are also indicated with dash-dot lines.
