Аннотация:Upper limits on large-scale anisotropy of the microwave background radiation are presented, obtained by dispersion, multipole and correlation analyses of the data from the "Relikt" space experiment. The dispersion analysis for the spectrum of perturbations gave the upper limit for the quadrupole component (ΔT/T)2 ≤ 2×10-5 and for the 6° scale (ΔT/T)30 ≤ 5.6×10-6. The multipole analysis gave the estimates of (ΔT/T)2 ≤ 3×10-5 and (ΔT/T)3 ≤ 7×10-5 for the quadrupole and octupole respectively. The autocorrelation function >ΔT1ΔT2< of the microwave background has been estimated for angular separations 20° - 150°.
