Color–color diagrams with photometric data from Table 2. Data are shown as red crosses, the giant and dwarf sequences (thin continuous lines) from Bessell & Brett (1988), the CTTS locus (Meyer et al. 1997), and a reddening vector of length A_V = 10 mag (Cohen et al. 1981) are overplotted. The dotted locus just above the dwarf sequence is the sequence derived from PMS stars in Luhman et al. (2010). Targets between the two dash-dotted lines can be dereddened to the PMS locus.
