Notes. (a)Bir20: Birky et al. (2020); Gra06: Gray et al. (2006); Jon06: Jones et al. (2006); Lew22: Lewis et al. (2022); May11: Mayor et al. (2011); Sto72: Stock & Wroblewski (1972); Tes16: Teske et al. (2016); Udr19: Udry et al. (2019).(b)Lewis et al. (2022) stated that ‘‘depending on the true period and eccentricity of the system, the minimum companion mass may fall in a range from 2 MJup to 50 MJup, making it a possible brown dwarf candidate”.
