Notes. The astrometric companion position components ΔRA and ΔDec are given relative to the respective host as detected with GRAVITY at the time of observation, tobs. ρ denotes the correlation between the two astrometric components while the rightmost column shows the companion over host contrast, (Fc/F*), in the K band after folding with the 2MASS/2MASS.Ks filter profile. Note the high K band contrast in the G ...0976 system.
