Histogram showing the mean detection level for void temperatures over the free parameters (void size, wavelet scale, and ratio of void radius) for each of our 1000 simulations using only voids with Δ_LOS < 0. The vertical line shows the same number for the real data. Results are shown for the Smica NO-SZ map where contamination from the SZ effect has been removed, the SEVEM cleaned frequency bands at 100GHz and 217GHz, the WMAP cleaned Q-band at 41Ghz, and the SEVEM cleaned map from the last PR4 Planck release.
