The time dependent analysis of the normal mode 3S2 near 1102.8 µHz allows a precise determination of the frequency and reveals a surprising phase modulation. This phase flip was first observed with the 10S2 normal mode and, by careless use of FFT, it may be misinterpreted as a frequency splitting. The correct demodulation requires the very robust method of homodyn conversion.
