In many cases, oscillating stars rotate so rapidly that second-order effects must be taken into account in analyses of the oscillation frequencies. Such investigations have commonly been based on results provided by Saio (1981) for a polytropic model. Here we compare those with frequency changes for more realistic models; we point out that a simple correction to Saio's data allows them to be used in the observationally relevant case of comparing models at fixed luminosity and effective temperature.
