Fig. 1


Distribution of the Tc slopes for the full sample (black solid line) and for the stars with |[Fe/H] |  < 0.1 dex (black dashed line). The position of the Sun is shown by the red dotted line. The expected distribution of the Tc slopes for 500 solar composition stars accepting the average abundance errors from Adibekyan et al. (2012c) is plotted with a red solid line.
