Near-IR ﹩{K}_{s}\,\mathrm{vs}.\,J\mbox{--}{K}_{s}﹩ color-magnitude diagrams for the VVV tiles 332 (left), 333 (center), and 334 (right). The stars indicate the sources of the sample microlensing events. The stars in green are the microlensing events with RC sources. The magenta star in the 333 CMD corresponds to the event with J mag above the detection limit. The arrows show the reddening vector after (Nishiyama et al. 2009).
