Notes.
the SFR from the [OII] line luminosity in the galaxy-integrated “1D” spectrum, obtained according to Kewley et al. (2004) calibration;
the total star mass obtained by SED fittings from CFHT B, R, and I bands photometric data using kcorrect (Blanton & Roweis 2007), corrected for a Universe with H0 = 70 km s-1 Mpc-1;
the surface densities associated to the gas mass, the star formation rate, and the star mass, calculated within R1/2, for example as ;
the extinction ratio AHα/A[OII]. AV, A[OII], AHα/A[OII], SFR24μm+UV and SFR[OII],B are given for information only. O’Donnell (1994) predicts that AHα/A[OII] is around 1.86 for a diffuse interstellar medium, and the variations here observed from one galaxy to the other are representative of the quality of the kcorrect fit. The comparison between SFR[OII], SFR24μm+UV, and SFR[OII],B gives an idea of the uncertainties in the SFR.
