Six additional sets of parameter chains were released for three models (ΛCDM+MNU,
ΛCDM+NREL, and WCDM) and two data sets (WMAP and WMAP+H0). Version 4.1 of the WMAP
likelihood software and RECFAST 1.5 were used.
Updated secondary parameters for models containing massive
neutrinos. The initial release had an error in the derivation
of the Hubble constant for these models (of order 2 km/s/Mpc),
so secondary parameters that depend on H0 had a small error.
The best-fit matter power spectra, P(k), are provided for all the supported model/dataset
combinations in the table. Each of these files has two columns. The first column is k/h in units of
Mpc^{-1}. The second column is the linear matter power spectrum P(k), defined such
that the variance is:
σ^{2} = (2π)^{-3} ∫d^{3}k P(k)

Three of the four new chains (lcdm/all, lcdm+sz=0/wmap, m2phi2/wmap) were updated by adding a
constant offset to the log likelihood to bring them into agreement with the convention adopted with
the other chains.

All of the entries were updated with better-converged chains in mid-2006.
These are denoted "v2p1" chains in the Table. The results of this reprocessing
did not materially affect any cosmological conclusions.
The following table entries have been updated with new parameter values and
chains to reflect the changes in the low-l likelihood and the point source
correction. These are denoted "v2p2" in the Table entries.
