Archival optical, NIR, MIR, and X-ray images of extragalactic FXRT candidates; the telescope or instrument plus filter and FXRT ID name are shown in the upper-left and upper-right corners, respectively. Each cutout is centered on the X-ray position, and red circles denote 3σChandra errors in the source localization. Columns 1–4: optical band (DECam, Pan-STARRS, and HST) images. Columns 5 and 6: NIR J or H and K (UKIRT or VISTA) images. Column 7: 3.4μm (unWISE) images. Column 8: X-ray Chandra (ACIS) 0.5–7 keV images.
