Remapping of positions of stars from colour-magnitude diagram (cmd) into plan T_eff versus dust relevance parameter r (see text) for sub-stellar objects with ages in the range 10–200 Myr. The upper panel shows results obtained using T_eff obtained from luminosities derived from the K band magnitudes and bolometric corrections from Filippazzo et al. (2015), combined with evolutionary radii. The lower panel shows T_eff from our remapping approach. In both panels, filled red circles are companions within 1000 au, filled black circles show companions outside 1000 au, and open diamonds show free-floating objects or very wide companions (separation >1000 au). The solid and dashed lines represent the expectations for AMES-COND and AMES-DUSTY models, respectively.
