Notes. Column (1): redshift range under study. Column (2): median number density of the sample. Column (3): observed cosmic variance. Column (4): dark-matter cosmic variance from the theory. Column (5): galaxy bias measured from the cosmic variance. Column (6): galaxy bias measured from the two-point correlation function by Hurtado-Gil et al. (2015).
