Simulated time series exhibiting the overall characteristics of the signals generated on the time distribution of sets H2 and T0 (upper and lower panels, respectively). The synthetic signal is shown by the black continuous line (in a yellow silhouette for better visibility). The signal parameters are P = 17.3 d, δ = 0.0005, t14∕P = 0.011, σ_T0 = 0.0002, and σ_H2 = 0.003 (see also Table 1). Only every tenth data point is plotted for H2 for clarity.
