Log SFR(L_IR) versus log SFR(Hα) for sources classified as Sa, Sb, Sc or Sd/Irr. Red dashed and continuous lines are the best fit to our data and the one-to-one relation, respectively. Also shown are the derived values for the slope (m) and its error (σ_m), as well as the scatter of the relation (σ) and the number of sources for each morphological type.
