Resolved maps of the three CO sources, 01a (left panel), 01b (middle panel), and 01c (right panel). Colors indicate the classification of each pixel based on the NUVrK and UVJ diagrams (Williams et al. 2009; Arnouts et al. 2013). There are no pixels classified as quiescent. Those classified as star-forming are shown in blue, cyan, or purple, and those classified as star-forming with high extinction–NUV−r > 9.2 − 2.1(r − K) or U − V > 3.8 − (V − J)–are in red, magenta, or orange.
