Relation between SFR and L_IR for various (sub) samples, with their respective error bars. The various samples are identified in the legend by the binning strategy (L_IR and SFR bins) and by the respective sample type (H-ATLAS and SFG). Solid lines represent the best-fitting relations for each sample, listed in Table 2, and correspond in color to the data points. The black dots represent SFR and L_IR for individual sources in the H-ATLAS sample.
