The scaling relations of SFR tracers for the three morphological classes, exploiting the H_α–FUV (left) and H_α–M_* (right) observations. Elliptical (dE/E/S0), spiral (S), and irregular (Irr) galaxies are shown as blue circles, green squares, and orange triangles, respectively. Uncertainties on the SFR tracers are inferred from the best-fit dispersion around the linear relations, as discussed in the text.
