6″ × 6″ three-band (F115W/F200W, F277W/F356W, F444W) colour images for each SCUBA-2 SMGs with the NIRCam-SMGs labelled. In each image we indicate the ID of the NIRCam counterpart(s) with 1, 4, and 32 SCUBA-2 SMGs having 3, 2 and 1 NIRCam counterparts respectively. It is clear that the sample of NIRCam-SMGs contains a broad range of morphologies from isolated disc and spheroidal galaxies to disturbed interacting systems. We indicate the 11 galaxies classified non-parametrically (and visually) as Mergers from Fig. 5 with an (M).
