Left panel: Log SFR – Log M_⋆ plane colour-coded according to the weighted average B/T in the bin. The white line represents the location of the MS of SFGs, and the error bars indicate its dispersion. Right panel: B/T ratio as a function of Δ_MS (distance from the MS) in different stellar mass bins. The dotted vertical line indicate the position of the MS. Error bars are obtained via bootstrapping.
