Summary of lensing-amplitude-measurement consistency tests using temperature-only reconstructions. Upper panel: difference between the measured lensing amplitude from pairs of reconstructions in units of the standard deviation of the difference from simulations. This tests whether the observed shifts are compatible with the behaviour expected from the FFP10 simulations. The lower triangle shows the amplitude measured from the conservative range 8 ≤ L ≤ 400, with a red colour indicating a larger amplitude of the reconstruction labelled on the left; the upper triangle uses the high-L range (401 ≤ L ≤ 2048), with red indicating a larger amplitude of the reconstruction labelled at the top. Numerical significances are quoted for those tests that show differences greater than twice the expected standard deviation. The first entry is our baseline temperature-only reconstruction; see the text for a description of all the other reconstructions. Lower panel: actual amplitudes (relative to our FFP10 fiducial model), with the result using the conservative range in blue and the high-L range in orange. The dashed lines show for reference the values in our baseline reconstruction.
