Average sensitivity limit in all filters for both NACO and Lick data. The limits were computed from the 3σ root-mean squared (rms) of the PSF radial profile for each target, and then averaged within each filter. The K_s filter for the NACO data is given for the S13 and S27 objective. The dashed lines represent our mass limits at 0.̋5, according to Baraffe et al. (1998) evolutionary tracks, assuming an average age of 30 Myr and a primary mass of 1 M_⊙.
