Reconstructions for the primordial power spectra from 100 simulations and Planck PR1 data. The 1σ and 2σ dispersion of the reconstructed spectra from the simulations are shown as blue bands around the mean of the reconstructions (blue line). We note that these bands do not include the errors due to point sources and beam uncertainties. The Planck fiducial power spectrum used for the simulations, with A_s = 2.215 × 10^-9 and n_s = 0.9626, is shown as a yellow dashed line. The inset shows a close-up of the main figure.
