Chandra 0.3–8 keV observations (left), model to the Chandra observations (middle), and combined Chandra and HST observations (right) of each of the dual AGN candidates. In all panels, north is up and east is to the left. The left and middle panels are centered on the coordinates of each SDSS spectrum. The left and middle panels are all ﹩5\prime\prime \times 5\prime\prime ﹩ except for the J0841+0101 and J1322+2631 panels, which are ﹩10\prime\prime \times 10\prime\prime ﹩. The left panels show one-fourth size Chandra pixels (purple), HST F160W contours (red), and best-fit locations of two X-ray sources (green crosses) that coincide within 3σ to the locations of two observed [O III] λ5007 components. The middle panels show the model fits to the two X-ray sources (purple). The right panels are four-color images of HST F160W (red), F814W (green), F438W (blue), and Chandra 0.3–8 keV (purple, one-twelfth size pixels smoothed with a 16 pixel radius Gaussian kernel) observations of the dual AGN candidates. The astrometric shifts described in Section 3.5 have been applied to properly align the Chandra and HST images.
