Notes. For the K1 and K2 bands, reported numbers are mean values and their random uncertainties (standard error of the mean). For all bands the values of the masses are derived using the BT-Settl Models by Allard et al. (2012) assuming an age of 35 Myr (see Sect. 3.3). Although the error on the mass is dominated by the uncertainty on the age, the listed values also take into account the contribute of the uncertainties on the photometry.
