This stellar mass catalogue was computed from the SDSS ugriz growth 
curve magnitudes as well as UV magnitudes from the work of Catalan et al., in prep. 
and NIR magnitudes from the 2MASS extended source catalogue. 
Not all galaxies have the same coverage, so some stellar masses will 
be the same as for the optical only catalogue. The stellar mass computation 
uses code and methods of Walcher+2008. Essentially
a library of star formation histories is used to produced a library 
of model SEDs. By computing chi2 for every SED, one derives the 
probability distribution for the different parameters, here 
stellar mass and absolute magnitudes. 

This catalogue uses the BC03 models with a Chabrier IMF. The library of 
model galaxies accounts for possible bursts and allows for different 
amounts of dust extinction.
