Comparison plots of the SED best-fit values of AV (top) and Rstar (bottom) against those reported in the literature. Literature AV values are compiled from the references listed in Table 4. Rstar values are derived from the spectral types reported in the literature, using the temperature conversion of Luhman et al. (2003b) and the 1 Myr evolutionary models of Baraffe et al. (1998) and Chabrier et al. (2000). Squares indicate Class I objects, circles indicate Class II objects, and crosses indicate Class III objects. The dotted lines represent fits that are 0.4, 1 and 2 times that of the literature values.
