Near-infrared color−magnitude diagrams of selected Pleiades candidates with two or more proper motion measurements. Symbols are as in Fig. 5. The solid line corresponds to the mean observed sequence of standard field late-M, L, and T dwarfs (Dupuy & Liu 2012) taken to the distance of the Pleiades. Spectral types are labeled. We show a semi-empirical, solar-metallicity, 120 Myr isochrone obtained as explained in the text (based on models by Chabrier et al. 2000a) with a magenta dashed line; related masses are also labeled in magenta in all panels. In the top panels, the BT-Settl 120 Myr isochrone based on synthetic colors (Chabrier et al. 2000a; Allard et al. 2012) is shown with a dotted line. Masses based on this model are provided on the right side in black. In the bottom panels, the NextGen (dotted line), DUSTY (dot-dashed line), and COND (dot-dot-dashed line) observable magnitudes are illustrated. The combined NextGen+DUSTY+COND 120 Myr evolutionary track (see text) is depicted with a brown solid line; masses given by this model are also indicated in brown.
