Mean-squared polarization fractions (〈p2〉) and inferred fractional polarization (⁠|$\sqrt{\langle p^2 \rangle }$|⁠) measurements for Nsource number of SPT–SZ selected sources stacked in flux bins Srange using 95 and 150 GHz SPTpol maps. There are four sources missing at 95 GHz due to smaller inverse noise variance weights at map edges. We show the unweighted (without any flux weighting) mean values for whole flux range as well. The error bars are evaluated using bootstrapping. We also show the flux weighted mean values, which is the best-fitting intercept, assuming zero slope for a straight line model fit to the mean-squared polarization fraction in five flux bins (see Section 4.1).
