⟨S_ph⟩ distribution in logarithmic scale for the GKM dwarfs, split into T_eff intervals of 300 K. The gray shaded histogram shows the distribution for the full subsamples, while the solid black and red lines show the histograms for the slow- and fast-rotating populations, respectively. For clarity, the distributions here are shown by the actual histograms, while we opt for the KDE for the remainder.
