Similar to Fig. 11 but for the SDSS E06/TB11 sample with T_eff < 40 000 K and S/N > 15 (black empty histograms). We also highlight the sub-distributions for 13 000 < T_eff (K) < 40 000 (blue histograms, radiative atmospheres) and T_eff < 13 000 K (red histograms, convective atmospheres). Binaries and magnetic objects were removed from the distributions.
