NISP-P example PSF in the HE-passband. This shows an initial shapelet reconstruction based on ~1400 unsaturated point sources, on a 6× oversampled grid (0705) compared to the native NISP pixel sampling. Clearly visible is the trefoil component that is present in all NISP images as well as VIS. A six-fold spike pattern becomes visible for brighter point sources towards or beyond saturation.
