. F IGURE . 1. The distribution of F stars in our sample from the observed distances from the Sun. Solid curve gives a power-law approximation of the number of stars as a function of the distance within R obs =50 pc and the dashed line is its extrapolation up to 60 pc. The arrow indicates the upper boundary of the domain where the sample is complete. discussion in the text | next figure .
