Fig. 3
HR diagram of NGC 2244. The evolutionary tracks and isochrones are from Meynet & Maeder (2003). They are computed for an initial rotational velocity of 300 km s-1. Triangles are the components of the binaries HD 48099 (cyan) and HD 6149 (pink). Stars belonging to NGC 2244 are shown in red/pink and stars from the Mon OB2 association are shown in blue/cyan. Arrows indicate upper limits on luminosities for SB1 and binary candidates.
