Notes. M_p and M_h denote the masses of the planet and its host star, respectively. D_L indicates the distance, while a_⊥ is the projected separation between the planet and the host. The quantities p_disk and p_bulge represent the probabilities that the planetary system is located in the disk and the bulge, respectively.
