Table 1: The statistical properties of the first scale (3 arc-min) diagonal wavelet coefficients distribution for the $\delta _{\rm T}$ map (KSZ + CMB), the KSZ map and the primary CMB alone. The two cases stand for our best case (first pair) and worst case (second pair). We note that the three moments are almost identical and characterise well the KSZ fluctuations; they are very different from the CMB fluctuation properties.
Table 2: Standard deviations of the KSZ maps and correlation coefficients between original and reconstructed KSZ maps for the same KSZ map with standard deviations ranging from $2.5\times 10^{-7}$ to $2.0 \times 10^{-6}$ . Two wavelet bases are tested.
