Notes. For each model, we report the 95% CL upper bound on the fractional primordial contribution of isocurvature modes at three comoving wavenumbers (k_low = 0.002 Mpc^-1, k_mid = 0.05 Mpc^-1, and k_high = 0.10 Mpc^-1), and the 95% CL bounds on the fractional contribution α_ℛℛ,α_ℐℐ, and α_ℛℐ to the total CMB temperature anisotropy in the range 2 ≤ ℓ ≤ 2500. We also report −2Δlnℒ_max for the best fitting model in each case, relative to the best fit 6-parameter ΛCDM model, with the number of additional parameters Δn. In the Gaussian approximation, −2Δlnℒ_max corresponds to Δχ². The general models have six parameters that specify the primordial correlation matrix at two scales k₁ and k₂, thus allowing all spectral indices to vary (so, four parameters more than the pure adiabatic model).
