Echelle diagram of the AIMS results for the fit of the individual frequencies (purple) and of the frequency ratios r₀₁ and r₀₂ (cyan). The modelled frequencies are displayed without a correction for the surface effects. The large separation (dashed black line) is computed with the observed frequencies (orange) and with the definition of Reese et al. (2012). The squares are radial modes, the circles are dipole modes, and the diamonds are quadrupole modes.
