False color F555W+F814W WFC3 images of the target galaxies, AGC 100288, AGC 102375, AGC 103435, and AGC 114959 (top left to bottom right). The large green dashed circles show the regions used to select GCCs, twice the half-light radius. Small red circles highlight GCCs that meet all selection criteria (Section 3). (a) Top left to bottom right: AGCs 115292, 124634, 181474, and 189298. (b) Top left to bottom right: AGCs 191708, 198686, 201993, and 258471. (c) Left to right: AGCs 312297 and 749387. Note that the late-type galaxy projected next to AGC 749387 is in the background at cz ≈ 20,000 km s⁻¹ (Adelman-McCarthy et al. 2008).
