Sample galaxy image at z = 5 at various stages of methodology, in a 60 × 60 pkpc² field of view. First panel: Result of SKIRT radiative transfer simulation. Second and third panels: Mock observation produced after regridding to 302 × 302 pixels based on Near Infrared Camera (NIRCam) resolution at this redshift and adding the effects of Gaussian + shot noise corresponding to S/N =5 and PSF is shown in the second panel with its respective segmentation map in the third panel showing only a single detected object. Fourth and fifth panels: Simulated imaging, as described earlier, but it is shown at S/N =15 in fourth panel, with its respective segmentation map and showing three distinct objects detected in the fifth panel.
