Diagrams showing the period-mass (top left), period-eccentricity (top right), mass-eccentricity (bottom left), and binary projected separation vs. planet semi-major axis (bottom right) relations for single stars with planets within the VHS area considered in this work and multiple-star systems with planets (filled symbols). Black dots represent known planet-host stars previously published in the literature whereas red dots with open squares show our three best new discoveries. Plots amended from the original version published by Eggenberger et al. (2004) and later updated by Mugrauer et al. (2007a), the lower right plot being added.
