A MF slope of Gamma = -0.8 +- 0.2 is obtained. Both datasets reveal a strong radial variation in the MF, with a flat slope in the cluster center, which increases with increasing radius.Presented at the IAOC Workshop on "Galactic Star Formation Across the Stellar Mass Spectrum" held in La Serena, Chile, March 2002; to be published in the ASP Conference Series, edited by J.
