Comparison of fitting with Eq. (7) (orange dashed line) and Eq. (8) (red line) in the 0.5 ≤ z < 0.8 redshift bin. The galaxies are shown as a number density plot, with dark red being high number density and dark blue low number density, and the size of the average error on SFR and M_⋆ is shown as a blue cross. There is very little difference in shape between the two fits, demonstrating that Eq. (8) is the preferred form of the MS.
