Abstract. The results of different analyses of the dynamical parameters of the Universe are converging towards agreement. Remaining disagreements reflect systematic errors coming either from the observations or from differences in the methods of analysis. Compiling the most precise parameter values with our estimates of such systematic errors added, we find the following best values: the baryonic density parameter _b h² = 0.019 ± 0.02, the density parameter of the matter component _m = 0.29 ± 0.06, the density parameter of the cosmological constant = 0.71 ± 0.07, the spectral index of scalar fluctuations n_s = 1.02 ± 0.08, the equation of state of the cosmological constant w < -0.86, and the deceleration parameter q₀ = -0.56 ± 0.04. We do not modify the published best values of the Hubble parameter H₀ = 0.73 ± 0.07 and the total density parameter _o -0.02^+0.03.
