Results of the outer masking experiments. The plots show the mean test scatter as a function of the diameter of the visible region around each cluster, for the five-filter case and the stacked image case, and for both the full sample and the sample without extreme ages. Dashed lines indicate the fixed guess baseline. These experiments provide the full set of complementary results to the inner masking analysis.
