Mock galaxy images in N UV, u, ɡ, r, i, ɀ, and y bands expected by CSST, with the colorbar showing the units as electron counts. The viewing angles are set to be 0° and 0° in inclination and azimuth for subhalos 0 and 31, while for subhalo 253881, the viewing angles are set to be at face-on and edge-on directions. For better illustration, the spiral galaxy is zoomed into a FoV with 200 kpc, and the edge-on images are rotated to make the galactic plane parallel to x-axis. Furthermore, the stellar mass, redshifts, and subhaloIDs are also displayed. The images are presented in logarithmic scale, and to mitigate the occurence of NaN values and enhance visual clarity, they are clipped at 10^-5.
