JHK diagram of the LkHα 186 cluster showing the stars detected in the IRTF J, H and K images. The solid and dashed lines are, respectively, the location of main sequence and giant stars from Bessell & Brett (1988) and the long-dashed line represents the CTTS location from Meyer et al. (1997). The dotted lines show the direction of the interstellar reddening vectors from Straižys et al. (2008). The stars with infrared excess are marked in Table 5.
