Frequency dependence of area of the SMHW coefficients. The plot shows the area of the wavelet coefficients at arcmin for different thresholds (from top to bottom: 3, 3.5, and 4), as a function of the frequency. The circles represent the values obtained for cleaned CMB maps obtained from the WMAP data at three cosmological frequencies (-, -, and -bands). The solid lines represent the areas, at different thresholds, for the noise-weighted QVW map.
