Left: number of stars within 50 pc showing a PMa S/N Δ_G2, with thresholds of 2, 3, and 5 (light blue, medium blue and dark blue histograms, respectively) as a function of the primary star mass m₁. The histogram of the overall sample is represented in light gray. Right: binarity fraction as a function of the primary star mass m₁. The binaries detected considering thresholds of Δ_G2 = 2, 3, and 5 are represented with light blue, medium blue, and dark blue lines, respectively.
