Fig. 5.
Left panel: histogram of the masses of the stars of our 50 pc sample that are present in the HIPPARCOS and GDR2 catalogs (dark blue histogram) and that are present in the GDR2 (with G < 13) but absent from Hip2 (light blue histogram). Right panel: completeness level of the sample of stars tested for the presence of a PMa as a function of their mass. The corresponding spectral types on the main sequence are shown in pink. The error bars represent the binomial proportion 68% confidence interval.
