Constraints on the reionization (mid-point) redshift z_re and σ₈ from a combination of Planck CMB power spectra and the lensing reconstruction, excluding low-ℓ polarization information. The grey band denotes the approximate z_re< 6.5 region excluded by observations of the spectra of high-redshift quasars (Fan et al. 2006). The lensing data significantly shrink the allowed region of parameter space, preferring lower values of the reionization redshift, in good agreement with the measurement from Planck low-ℓ polarization.
