For each SLACS lens used in our analysis, we show the observed stellar velocity dispersion profile and the best fit found in the hierarchical analysis. The data for individual lenses is described very well by our model when applied to a single lens. However, in the hierarchical analysis, they were all required to share a single population-level value of λ_int (Section 7) with the time delay lenses and among each other. The offsets between the data and the best-fit model are due to mismatches between the population-level value of λ_int and the individual λ_int that would be required to fit each lens separately. The offsets are reflected in the non-zero scatter in λ_int found for the SLACS population.
