Relative frequency differences between pulsation calculations in the N = 3, Ω = 0.58946223Ω_K polytrope from Reese et al. (2006) and an equivalent model from the present method as a function of the oscillation frequency (expressed in units of the Keplerian rotation rate, Ω_K). The different colours indicate the harmonic degree of the oscillation modes that are carried over from the non-rotating case. All azimuthal orders (|m|≤ℓ) are provided for each degree.
