PRIMER | The power of fully-sampled NIRCam imaging. Left: simulated NIRCam image of a clumpy z = 2 galaxy in the F277W filter with the native NIRCam-LW pixel scale (0.063 arcsec). Right: NIRCam image of the same galaxy in the same filter but this time with sub-pixel sampling, and image reconstruction with 50% smaller pixels. Not only are the structural details much clearer, but several compact clumps are simply not detected in the left-hand undersampled image: properly sampled imaging enhances the detection of faint compact objects (such as extreme redshift galaxies), as well as improving the precision of morphological studies
