The four panels on the left show the G-M₂₀ values for the FUV rest-frame redshifted images. For each redshift bin, we connect the G-M₂₀ values from an objectʼs lower redshift (gray) to its higher redshift (open circles) as defined in the legend. The two panels on the right show the average G and M₂₀ values with simulated redshift (black circles). The vertical lines span the minimum and maximum values for that redshift bin. The dashed and solid lines illustrate the trend for G to decrease and flatten with increasing redshift, while M₂₀ remains relatively stable.
