Notes. ⁽¹⁾ ppt = parts per thousand = 0.1%. ⁽²⁾ Normalized phases corresponding to BJD_TDB 24 51 470.476568 (1st datum). ⁽³⁾ For the p-modes, frequencies and periods are the mean values in the period 1999–2012, corresponding to BJD_TDB ~24 54 090 (or year ≈ 2007.0), which is the weighted mean time. We note that in 10 years of observation, the secular variations of the pulsation frequencies and periods are larger than the 1σ errors reported here, obtained from a Monte Carlo simulation assuming constant frequencies. ⁽⁴⁾ Because of the noise in the Fourier transform at low frequencies (Fig. 11), the multi-sinusoidal fits for the g-modes are less stable than those for the p-modes, and therefore the 1σ frequency/period errors for the g-modes reported here are underestimated.
