Total granulation amplitudes and characteristic frequencies as a function of v_max obtained for the three background models of Table 1. In all panels, the dashed lines represent the corresponding scaling relation for the parameter from Kallinger et al. (2014). Top row: total granulation amplitudes colour-coded by the stellar metallicity [Fe/H] for the 727 stars with available temperatures. The black lines show a power law fit to the data. Bottom row: the characteristic frequencies of the individual granulation components for the 749 stars with consistent granulation posteriors, with colours as indicated by the legend. The corresponding coloured lines show the results of a power law fit to the data for each timescale, all given a black outline for improved readability.
