Comparison between the distributions in the M sin i-a parameter space of the M sin i > 40 M_Jup companions orbiting the 132 stars in the sample for which we performed simultaneous radial velocity and proper motion anomaly fits. The blue dots and histogram show the parameter space position and distribution of semimajor axes and minimum mass, respectively, as retrieved by the radial velocity analysis alone, while the respective red plot elements refer instead to the results of the simultaneous astrometry and radial velocity fits, and, therefore, true dynamical mass instead of minimum mass. The components of multiple systems are connected by gray dash-dotted lines, while the horizontal dashed brown, orange, and yellow lines respectively indicate the brown dwarf (40 M_Jup), dwarf star (80 M_Jup), and solar-mass (1047.58 M_Jup) thresholds.
