Summary of internal consistency tests between our fiducial minimum-variance (MV) reconstruction and a set of alternatives designed to test sensitivity to potential issues. The top panel shows estimates, with measurement error bars. The bottom panels show the residual with respect to the MV reconstruction in units of the MV measurement uncertainty. The grey band marks the 1σ deviation uncertainty of the MV reconstruction. The error bar on each data point in the lower panels gives the standard deviation of the scatter between each result and the MV, determined from Monte-Carlo simulations that account for the correlated CMB, noise and foreground power between estimators. Comparison of the uncertainty on the scatter points and the grey band gives an indication of how constraining each test is. The various tests are described in more detail in subsections of Sect. 7.
