Visualizing Hubble residual STD values (upper panels) and mass step values (lower panels) from simulations in Tables D.1 and D.2 (left panels) and data in Table D.3 (right panels). Nomenclature in the x-axis labels goes as follows: filters fit are given along with a descriptor such as “fixx1c” which corresponds to fixed x₁ and c, “fixc” which corresponds to fixed c and fitted x₁, or no descriptor which corresponds to fitted x₁ and c. This is an expansion of Fig. 2.
