Distributions of the Galactic orbital parameters and space velocities of the stars with Neptune-mass planets (shaded blue), with Jupiter-mass planets (red dashed line), stars without planets and [Fe/H] > −0.6 dex (black dotted line), and stars without planets with [Fe/H] > −0.6 dex and υ_pec < 20 km s^-1 (green dotted-dashed line). The distributions of different groups were set lower/higher for the sake of clarity.
