local galaxy sample

• galaxy zoo data [1]

• Galaxy Zoo DECaLS[2]
• stamps of SDSS main sample galaxies(r<17.77) in DESI [3]

high z galaxy sample

• COSMOS F814W galaxy postages
• CANDELS 5 fields galaxy postages

Mock galaxies

• generate using GalSim (with CSST-like survey parameters)

• tel_diam=200mm, exptime=150s, lam=5500A, sky_mag=23, psf_sigma=0.2, gain=1, readnoise=5, pixel_scale=0.074

• generate using GalSim-Hub[4]
