Left: distribution of total stellar masses obtained from the spatially resolved spectral fits of each galaxy. Black bars mark galaxies with C < 2.8, gray bars those with C ≥ 2.8. Center: correlation between the total stellar mass and SDSS r-band total magnitude. Right: comparison of the masses estimated from our analysis (horizontal axis), from SED fitting of integrated SDSS photometry (blue circles), and SDSS+2MASS (red) bands using the code explained in Walcher et al. (in prep.) gray points show the comparison with masses obtained fitting the SDSS photometry with the k-correct routine of Blanton & Roweis (2007). The photo-SED masses are obtained assuming a Chabrier IMF, while the starlight masses are for a Salpeter IMF. The dashed blue, red, and gray lines show the best linear fits, while the solid black line is the one-to-one relation. The dashed black line is the one-to-one relation shifted by 0.25 dex to account for the expected offset due to IMF.
