SDSS-V’s stellar companion mass sensitivity. The 3σ detection limit as a function of semimajor axis and secondary mass. The detection limit assumes a 1 M⊙ primary and circular orbits. For the RV limits, ﹩\sin i=1﹩. The SDSS-V APOGEE instrument has an RV precision of 30 m s−1. The DESI SV 1 survey has an RV precision of 1 km s−1 (A. P. Cooper et al. 2023), and Gaia RVS DR3 has an RV precision of 1.3 km s−1 (D. Katz et al. 2023). The Gaia astrometric precision is 0.02 mas (L. Lindegren et al. 2021), and the 3σ sensitivity is calculated for a system at 60 and 100 pc in distance from Earth. The dotted horizontal lines are at 13 and 80 Jupiter masses, respectively.
