Notes. Summary statistics of the 
values computed for weighted subsamples of control with the level of EVPA difference uncertainties (
) matching those of target and of size equal to the size of target (referred to as target-like MC), compared to the observed
value of target. The probability that 
arises as a random realization of a 
-matched
control subsample of equal size to the size of target is also quantified in terms of a
p-value for each case studied. The information is presented both for PR3 and SRoll2 polarization maps and when removing the CMB polarization as estimated from the different Legacy component-separation methods. Results are shown for both implementations of the target pixel selection presented in Sect. 4.1. We also provide the results for the case of no CMB removal.
