Notes. The errors correspond to ±1σ. The asterisk marks the objects that are also in the spectroscopic sample.
From Caballero-Nieves et al. (2014) and Maryeva et al. (2016): Schulte 12 has a detected companion with a separation ρ = 65 ± 1 mas, a position angle PA = 293.0 ± 0.3°, and with Δ mag = 1.79 ± 0.02. ( † )The names of the stars were shortened for practicality, and these objects must be read as [GKF2010] MN 46, [GKF2010] MN 48, and [GKF2010] MN 64.
