Correlations between ν_max (determined using Eq. (4)), the corner frequency, and the flicker frequency. The corner and flicker frequencies have been derived for each Kepler target using the MCMC analysis described in Sect. 4.2. The color code indicates the apparent magnitude of the target: m_v < 10 (black) and m_v > 10 (gray). Solar values derived from VIRGO observations are shown by the yellow star in each panel. Pearson (ρ_P) and Spearman’s (ρ_S) coefficients associated with these plots are indicated on each panel.
