Distributions of τ_cz/𝒯 for the glitch signature in the frequencies (left panels), second differences (middle panels), and r₀₁₀ ratios (right panels) for the Kepler star KIC6679371 (in light grey). 𝒯 = 1/(2Δν) is the total acoustic radius of the star. The results for the r₀₁₀ ratios are converted from the measured t_cz with τ_cz = 𝒯 − t_cz. The light grey histograms are obtained by a fit of the observed data with the standard expressions (Eqs. 9, 10, 12). For clarity, the top panels represent the observed distributions alone. The green curve represent the resampled Fourier transform of the synthetic data. The red dashed vertical lines indicate the position of the BSCZ as inputted in the synthetic data. The black down arrows show the peak in the histogram of the observed distribution selected to generate the synthetic data.
