Effectiveness of weighted resampling in producing target-like MC draws from control with noise properties matched to target: means and standard deviations per bin of normalized histograms of for target1-like MC samples (blue), overplotted on the distribution of those uncertainties for the observed target1 sample (orange). The shaded blue area marks the plus and minus one standard deviation around the mean calculated in each bin from 10000 target1-like MC draws obtained through weighted bootstrap resampling of control. This corresponds to sampling uncertainties. The continuous blue line marks the mean in each bin. Very similar results are obtained forthe target2 sample and for all combinations of sets of polarization maps and CMB estimates.
