5′ × 3′ VVV K_S image of Pismis 24 area (large circle). The probable subclusters VVV CL165 (top circle) and VVV CL166 (bottom circle) are indicated. The small red circles indicate YSOs (Fang et al. 2012). The shift between the stars in the VVV image and the YSOs from the catalog of Fang (2MASS data) is a consequence of the difference of angular resolution of each survey, 0.34′′ and 2.0′′ respectively. The radius of the black circle is given in Table 1.
