Notes. The stellar masses and their projected separation (ρ) are in the third, fourth, and fifth columns, respectively. The index 1 in the masses indicates the member of the binary system harbouring the planetary system. The mass of the secondary stars indicated with “RD” (red dwarf) corresponds to the range 0.08−0.5 M⊙. The second and last columns indicate the number of exoplanets and semi-major axis (ap) of the most external planet orbiting the main star (m1).
