Notes. Shifts are given in units of the posterior width rescaled by 
. If the parameters were uncorrelated, 68% of the shifts would be expected to lie within ± 1σ. The effect of varying the value of ℓmin is measured on the likelihood of the average spectra over 300 realizations, labelled 
. A significant decrease of the bias on ns is obtained by not including low-ℓ multipoles, at the cost, however, of a degradation in the determination of the foreground amplitudes , , and .
