Present day mass function of all hot luminous stars classified spectroscopically and photometrically (Sp+Ph) in the R136 region (top) and in 30 Dor (bottom). Hatched regions indicate where the mass function is based solely on stars classified spectroscopically (Sp). A Salpeter α = −2.3 slope is overlaid with a yellow line (solid = Sp+Ph, dashed = Sp), for which the integrated mass (>20 M⊙) is consistent with that of each region.
