This stellar mass catalogue was computed from the SDSS ugriz Petrosian
magnitudes as quoted in CALIFA_8_MS_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 NED from the 
"V (Virgo + GA + Shapley)" velocities. See NED and Mould et al., 
2000, ApJ, 529, 786 for details on the derivation. 

This catalogue is identical to CALIFA_6_MS_GC_Mstar_optical.csv but for the 
magnitudes used. Here it is SDSS Petrosian, there it is growth curve magnitudes 
from Walcher+14.
