SEDs of the four stars that have been classified by their optical spectra. The X-shooter spectrum of each star (black line) is dereddened (blue line) with the A_V value listed in Table 2. The corresponding Kurucz model is plotted in gray. Optical (Zacharias et al. 2005; Monet et al. 2003), SOFI, and IRAC photometry is overplotted with squares. The “kinks” in the spectra at 0.35 and 0.85 μm are instrumental features.
