Notes. The measured overall lensing amplitude  is given for the conservative (40 ≤ L ≤ 400) multipole range, as well as the lower signal-to-noise bins on either side. The difference between the test amplitudes and the corresponding MV result (with amplitudes of , , and for the three multipole ranges) is given as ΔMV. The quoted uncertainty on the difference is obtained using Monte Carlo simulations and therefore accounts for any correlations between the MV and test estimates. The PTE values are estimated by comparison of the χ2 values to the distribution from simulations. PTEs are given for the square of the overall amplitude difference, as well as for the χ2 of the difference between the bandpowers of the binned spectra.

(†)

Comparison is against the SMICA polarization-only reconstruction, rather than the MV reconstruction.

(††)

Comparison is against the SMICA TT reconstruction, rather than the MV reconstruction.

(†††)

This test only involves a change in the simulations used to perform the debiasing corrections and estimate error bars. We have quoted the scatter between the two sets of simulations, although this is an upper limit on the difference that we should actually see for the data.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
