Tables of the power spectrum of CMB anisotropies in the form of $C_\\ell$'s as a function of $\\ell$ are presented. Although the Harrison-Zeldovich initial spectrum is assumed in these tables, we present simple approximations for obtaining the $C_\\ell$'s corresponding to a tilted spectrum from those with a Harrison-Zeldovich spectrum.
