Notes. All planets from the Butler et al. 2006 catalog with $M_{\rm c}\sin i< 4$ $M_{\rm J}$ (1), companions with $4 < M_{\rm c}\sin i< 10$ $M_{\rm J}$ (2), companions with $10 < M_{\rm c} \sin i< 80$ $M_{\rm J}$ but excluding those with confirmed mass higher than 80 $M_{\rm J}$ (3), and companions with true masses in the range $10 < M_{\rm c}< 80$ $M_{\rm J}$ (4).
