CMDs of young stars in each subregion. Black curves show the best-fit isochrones for subregions A–D. Stars fainter than 18 mag (gray shading area) are excluded from the CMD fitting. Subregions E and F are not fitted because of the limited number of young stars. The blue-gray dashed curves indicate the reference theoretical isochrones.
