Color images (g′, r′, i′ filters) showing the effect of the perturbed values from fiducial for each parameter, as listed in Eq. (29). For each subplot we only added or removed the offset for one parameter listed in Eq. (29) and kept the other at its fiducial value. Decreasing the value of M^* (top right) increases the number of galaxies. Decreasing the value of log₁₀(ϕ^*) decreases the number of galaxies. This shows that these two parameters are highly correlated.
