The log-KLD and EMD of posterior samples of w at different values of the FOM₃ classification metric for each contaminating class (color) and observing strategy (panel). The vertical lines within the WFD panels indicate the minimum and maximum values among ten different realizations. Despite the considerable variability between realizations, the cosmology metrics do exhibit consistent sensitivity to the impact of different classes of contaminant at a given contamination level. Examples of this effect manifest as stratification among the classes at a given FOM₃ value.
