Query: On TP-AGB stars and the mass of galaxies   Recent calculations of evolutionary tracks of TP-AGB stars of different mass
and metallicity by Marigo et al. (2007) have been incorporated in the Bruzual &
Charlot evolutionary population synthesis models. The mass of the stellar
population in HUDF galaxies at z from 1 to 3 determined from fits to the
spectro-photometric data of these galaxies is 50 to 80% lower than the mass
determined from the BC03 models. The ages inferred for these populations are,
with exceptions, 40 to 60% of the BC03 estimates.
