Notes. The first three rows show results using as lensing tracer the temperature-only quadratic estimator (
), the minimum-variance estimator combining temperature and polarization (
), and the GNILC CIB map at 545 GHz. We also show the expected efficiencies, as predicted from the FFP10 simulations, and the reduced χ2 (
, for ν = 17 
and 9 (
) degrees of freedom) for the best-fit efficiencies estimated from the delensed spectra. The next two rows show the results obtained combining these tracers, and the significance of the improvement found over the most efficient single tracer in the combination. This delensing of 
(last column) does not actually reduce the total B-mode power (in contrast to the template delensing of Table 3), but isolates the delensing signature using subtraction of the fiducial biases explained in the text.
