G − M₂₀ plane as a function of redshift in CANDELS. The estimates of the coefficients obtained from the observed data are plotted in red, while the corrected coefficients are represented in blue, and the coefficients from bin 0 are shown in gray. As a reference, the orange lines displayed on the plot indicate the boundaries defined in Lotz et al. (2008) to classify galaxies into early-type, late-type and mergers in the G − M₂₀ plane.
