Examples of Sérsic fits and residuals of CRISTAL galaxies observed in JWST/F444W (rest-frame 0.7 μm at z ∼ 5). North is up for all images. For galaxies with multiple components, we simultaneously fit all components, each characterised by a single Sérsic profile. The resulting half-light radii (R_e), Sérsic indices (n), and position angles (PA, measured counter-clockwise from the north) are listed in Table B.1 and annotated in the figures in order of increasing R_e. Except in a few cases, such as CRISTAL-09, 12, and 14, the residuals exhibit clumpy structures and asymmetries in the light distributions due to multiple discrete clumps.
