Comparison of cosmological parameters derived from the FFP6 simulation using different methods. The parameters shown as blue, red and green points indicate results obtained with ℓ_max = 1500, 2000 and 2500, respectively, and the yellow points show the results derived by CamSpec and Plik using cross-spectra. The black horizontal lines mark the input parameter values. The values of the foreground parameters are not shown for CamSpec or Plik  since they use a different model. The matter power spectrum pivot scale was k = 0.002 for all likelihoods, except CamSpec for which k = 0.05 was used.
