Notes. Fits to SFR−M★ using the methods described in Sect. 4. Each column shows the values of the y intercept (α), slopes (β), and scatter (ϵ). For each redshift bin, we distinguish between the global and low-M★ galaxy regimes, as defined in Sect. 4. The typical uncertainties found for α are ∼0.1; ∼0.01 for β and ϵ.
