RESULTS AND ANALYSIS Mass determination

Star Formation Histories of z <0.25 Galaxies from GALEX Samir Salim (UCLA) and the GALEX Science Team. RESULTS AND ANALYSIS Mass determination Kauffmann et al. determined masses using SDSS spectra (Hdelta & D4000) Comparison with our determination: Relative scatter 0.11 dex
