Table 2: Blue-to-red phase differences of f and its first harmonic together with estimates for $\ell$ and m for f₁, f₂ and f₃ (Telting & Schrijvers 1997). The phase differences $\Delta \Psi$ are given in $\pi$ radians. Due to the bad quality of the IPS diagnostics associated to 2f₃ (see Fig. 6), we cannot provide information on the m-value of this mode.
