Color–magnitude V versus B – V diagram for stars observed toward LMC N191. Three isochrones are shown, 3 Myr (A_V = 0.9 mag, green dashed curve), 8 Myr (A_V = 1.2 mag, violet dotted curve) and 1 Gyr (A_V = 0.3 mag, blue thick dashed curve), computed for a metallicity of Z = 0.008 (Lejeune & Schaerer 2001) and a distance modulus of 18.53 mag. The red cross indicates the location of the main exciting star of N191A. The numbers refer to the stars listed in Table 2.
