SFR_{This work}−M_⋆ relation for star-forming galaxies compared with previous theoretical and observational works. Comparison with observational studies: Panel a) SFR-M_⋆ fits to the running median for bins of 2000 objects obtained in this work (red solid line) and from the SDSS fibre (brown dashed line), together with the values provided by MPA-JHU (blue dotted line), using the Hopkins et al. (2003) recipe (orange solid line), and from our refined method of Hopkins et al. (2003) recipe (orange dashed line). Panel b) Difference vs. M_⋆ between SDSS fiber SFRs and SFR_{This work} and between observational studies and SFR_{This work} (colours as in upper left panel). Dotted line shows Δlog (SFR) = 0. Comparison with theoretical studies: Panel c) SFR-M_⋆ fits to the running median for bins of 2000 objects obtained in this work (red solid line) and from the SDSS fibre (brown dashed line), together with the predictions from Sparre et al. (2015) (green dashed line) and Dutton et al. (2010; cyan dashed line). Panel d) Difference vs. M_⋆ between SDSS fiber SFRs and SFR_{This work} and between theoretical predictions and SFR_{This work} (colours as in upper right panel). Dotted line shows Δlog (SFR) = 0.
