This stellar mass catalogue was computed from the SDSS ugriz Petrosian
magnitudes as quoted in CALIFA_8_ES_SDSS_optical.csv using 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.

The redshifts in column 3 have been obtained from the CALIFA V500 cubes. 

The magnitudes used are SDSS Petrosian, i.e. exactly the same as in the 
catalogue CALIFA_9_MS_SDSS_Mstar_optical.
