Notes.

(b)

Available data: SOFI (JHKs), IRAC (bands 1234), SINFONI (S), X-shooter (X).

(c)

Based on comparison with reference spectra from Rayner et al. (2009). For objects 1, 3, and 10, see Sect. 4.1.

(d)

Evolutionary class (Lada 1987) derived from IRAC colors as defined by Megeath et al. (2004); Gutermuth et al. (2009).

(e)

From Kenyon & Hartmann (1995), averaged between the spectral type range. For objects 1, 3, and 10, see Sect. 4.1.

(f)

Adopting a distance of 0.7 kpc.

(g)

Derived using intrinsic colors of Kenyon & Hartmann (1995) and Martins & Plez (2006). For objects 1, 2, 3, and 10, SED-fitting was used (Sect. 4.1).

(h)

Result of fitting with Kurucz model (Kurucz 1993).

(i)

Result of interpolating evolutionary tracks and isochrones (Siess et al. 2000; Da Rio et al. 2009; Ekström et al. 2012).
