Abstract
We use GALEX far-ultraviolet (FUV, 1539 angstrom) and Ha data for a large sample of nearby objects to study the shape of the initial mass function (IMF) of normal late-type galaxies in the high mass (m >= 2 M circle dot) stellar range. The data are corrected for dust attenuation using the most accurate techniques at present available, namely the Balmer decrement for H alpha data and the total far-infrared to FUV flux ratio for GALEX data. The H alpha to FUV flux ratio of the observed galaxies increases with their total stellar mass by a factor of similar to 1.4 dex in the stellar mass range 10(7)
