Power density spectra with overlaid results of the background model inference using model H (see Table 1) when binning to 0.5 μHz resolution for three stars: KIC6679371 (top), KIC8866102 (middle), and KIC8006161 (bottom). The unbinned PDS is shown in grey with the binned version overplotted in black. The model is plotted in red using the median of the obtained posteriors for each fit parameter. Additionally, 50 randomly drawn samples from the posteriors are used to replot the model to indicate the scatter. The individual granulation components are plotted as dashed green profiles. The fitted value of v_max is given in each panel and indicated by the vertical dashed black line, while the noise is shown by the horizontal dashed orange line. The activity component is the dash-dotted green line. The model without the influence of the Gaussian oscillation excess is plotted as the dashed blue profile, visible underneath the oscillation excess.
