(a) CMB cleaned map derived from the 4th release of the WMAP data, obtained via the template fitting technique described in [75]. (b) wavelet coefficients of the previous map, obtained after the SMHW convolution at a scale of 𝑅=250 arcmin. The location of the Cold Spot is indicated in both panels by the circle. The centre of the Cold Spot is 𝜃=147^∘ and 𝜙=210^∘.
