SFR–M^∗ plane. Grey points are all galaxies in the sample analysed in this work, black dots are galaxies in the same sample with spectroscopic redshift, and red circles are galaxies that are outliers in redshift. Each column shows a different redshift bin: (left), (central) and (right). The vertical black dotted lines are the 90% completeness limit in stellar mass in each redshift bin. The horizontal dotted black lines are the 3σ detection limit in SFR in each redshift bin.
