“…Strictly speaking, we should analyze the full DMR data set to obtain the correct normalization. Bunn and Sugiyama (1995) applied Bayesian analysis on the DMR 2 year data. They obtained the maximum likelihood value of Q rms PS for CDM models.…”

Cosmic microwave background (CMB) anisotropies and density uctuations are calculated for at cold dark matter (CDM) models with a wide range of parameters, i.e., 0 ; h and B for both standard recombination and various epochs of reionization. Tables of the power spectrum of CMB anisotropies in the form of C`'s as a function of`are presented. Although the Harrison-Zeldovich initial spectrum is assumed in these tables, we present simple approximations for obtaining the C`'s corresponding to a tilted spectrum from those with a Harrison-Zeldovich spectrum. The 8 values are obtained for the matter density spectrum, with (10 ), xed Q rms PS and COBE DMR 2 year normalizations. Simple modi cations of the tting formula of the density transfer function which are applicable for models with high baryon density are given. By using both numerical results and these tting formulae, we calculate the relation between 8 and Q rms PS , and nd good agreement. Velocity elds are also calculated.

“…Values of the most likely Q rms PS of at CDM models with the n = 1 initial spectrum, h = 0:5 and B = 0:03 as a function of 0 . Bayesian analysis of COBE 2 year data(Bunn and Sugiyama 1995) is employed. Solid and dashed lines are the cases including and excluding quadrupole data, respectively.…”
