Left panel: the K_S vs. (J−K_S) color–magnitude diagram of DBS2003 179. All stars in the field of view are shown as light circles, while the cluster members are plotted with bold circles. The theoretical main sequence from Schmidt-Kaler (1982) is drawn with a solid line corrected for the adopted distance modulus of (m−M)₀ = 14.5 mag and E(B−V) = 5.4. Stars with known spectral types are labeled. The large circle and the triangle schematically mark the zones of WR and OV class stars, respectively. Right panel: K_S vs. (H−K_S) color–magnitude diagram. The solar-metallicity Geneva isochrones (solid lines) of 2 (green), 3 (red), and 5 (blue) Myr (Lejeune & Schaerer 2001) and the corresponding PMS isochrones (dashed lines) from Siess et al. (2000) are shown.
