Relation between gas surface density (Σ_gas) and SFR surface density (Σ_SFR) within the disk of NGC 1313 (the purple filled stars) overplotted on the relation for individual galaxies in Fig. 2 of Daddi et al. (2010b). The red and light blue filled circles are infrared-luminous starburst galaxies and normal spiral galaxies from the sample of Kennicutt (1998). The orange open diamonds and boxes are SMGs (Bouché et al. 2007; Bothwell et al. 2009). The blue filled boxes are z = 1−2.3 normal galaxies (Tacconi et al. 2010). The cyan filled circles are the BzK galaxies (Daddi et al. 2010a). The solid and dash-dotted lines are the same as those in Daddi et al. (2010b); the solid line shows a fit to normal spirals and BzKs galaxies with the K-S law model (N = 1.42), while the dash-dotted line shows the same relation shifted up by 0.9 dex to fit starburst galaxies and SMGs.
