Hace 11 horas · Third, as the surveys overlap in sky regions and redshifts, cosmological signals and systematics are correlated (e.g. between CMB foregrounds and the galaxy distribution), thus requiring different astrophysical observables in the simulations to be correlated with each other. Finally, to minimize the variance of measured statistics and to
