VVV observed (J − K_S) vs. K_S CMD extracted from the region of VVV CL036. The most probable cluster members are plotted with filled circles and the filled rombs and crosses stand for the equal area two randomly selected comparison field stars. The continuous line represents the sequence of the zero-reddening stars of luminosity class V (Schmidt-Kaler 1982). Reddening vector for A_V = 21 mag is also shown.
