We derive a dynamical mass of 1.2 ± 0.1 × 106 M⊙ for the young SSC M82-F and determine that the current (LV/M)⊙ is a factor of ∼ 5 higher than that predicted by a standard Kroupa (2001) IMF. This suggests that M82-F has a deficit of low mass stars and will not survive to become an old globular cluster.
