Notes. The age ranges listed were used to calculate theoretical masses in the last column predicted by the models for the given absolute magnitude in 2MASS K-band. The magnitudes listed in the fourth column are derived from the unresolved 2MASS K-band magnitudes of the system and the flux ratios in the SPHERE or SINFONI K-bands, and the name convention of K′ is applied to mark this difference. For J0437 we used the flux ratio from the Keck/NIRC2 K-band observations from Montet et al. (2015).
