For the star forming and unclassifiable galaxies we calculate dust extinctions from the UV slope, the H$\alpha$/H$\beta$ ratio and the $L_IR/L_UV$ ratio. There is a tight correlation between the dust extinction and both $L_IR$ and metallicity. We calculate SFR$_total$ and compare it with other SFR estimates (H$\alpha$, UV, SDSS) finding a very good agreement between them with smaller dispersions than typical SFR uncertainties. We study the effect of mass and metallicity, finding that it is only significant at high masses for SFR$_H\alpha$. For the AGN and composite galaxies we find a tight correlation between SFR and L$_IR$ ($\sigma\sim$0.29), while the dispersion in the SFR - L$_UV$ relation is larger ($\sigma\sim$0.57). The galaxies follow the prescriptions of the Fundamental Plane in the M-Z-SFR space.
