Size‐magnitude diagrams for the 12 galaxies that have significant diffuse source excesses, listed in Table 1. Using the algorithm described in the text, we assign a GC probability based on its position in the ﹩r_{h}- z_{0}﹩ diagram. Objects are color coded by their probability of being a globular cluster. On the left are the objects in our program fields, and on the right are the objects in the custom control fields for that galaxy, scaled to a single field. Each one of these galaxies shows at least a 3 σ excess of diffuse sources as compared to the control fields.
