We assume an open universe and consider as primordial power spectrum the Harrison-Zeldovich one, $P(k)=Ak$. We find that the flatness of the universe is not implied by the data. The quadrupole normalization amplitude, $Q_{rms-PS}$, is related to the density parameter, $\\Omega$, by $Q_{rms-PS} = 10.67 + 55.81 \\Omega - 128.59 \\Omega^2 + 81.26 \\Omega^3\\ \\mu$K.
