:*The Carnegie-Irvine Galaxy Survey (CGS) is a long-term program to investigate the photometric and spectroscopic properties of a statistically complete sample of 605 bright (BT < 12.9mag), southern (δ < 0°) galaxies using the facilities at Las Campanas Observatory.

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]
  • A sample of CGS galaxies[5] manually move to high redshifts and mocked in other surveys(PS1, SDSS stripe82, CANDELS_AEGIS , Hubble Frontier Fields) , contact ssy@shao.ac.cn for more information
