Scientific paper

We extend previous work on the statistics of observables describing the large-scale anisotropy of the cosmic microwave background (CMB). We focus on the two-point angular correlation function, on the low-order harmonic multipoles, and on differential measurements of the CMB anisotropy. Here we consider flat models, as cold dark matter, with adiabatic scale-invariant density fluctuations, as well as an open pure baryonic universe, with initially isocurvature fluctuations. We improve the theoretical discussion with a detailed treatment of the effect of the experimental noise. This allows us to develop a method to set statistically sound upper limits to the CMB anisotropy level as a function of the SNR. For a COBE-like experiment, with a pixel sensitivity of about 4 x 10 exp -5, one can set upper limits to the ensemble average quadrupole, correlation function at 12 deg, and differential anisotropy at 60 deg.
