Model comparison metrics (from left to right: maximum likelihood, deviance information criterion, Akaike information criterion) for the different models we considered (prj: projection effects, cont: contamination, mass dep: mass-dependent scatter, prj+: projection effect with free amplitude, prj++: projection effects with free amplitude, richness and redshift trends, prj+cont: projection effects with contamination). Each entry is the difference between the model in the row and the model in the column. Negative values (in blue) mean that the model in that the row is preferred.
