Fig. 20


Constant feature model results for both T-only and T+E data across a wide frequency range. The upper four panels show the feature signal in the Modal range 0 <ω< 350. The two upper left panels show contours of the raw significance σ obtained from the SMICA map as a function of the frequency ω, for T-only and T+E, respectively. The upper right panels show the maximum signal after marginalizing over phase φ for both T-only and T+E for all foreground separation models. The third and fourth panels show the maximum feature signal in both T-only and T+E across the frequency range 0 <ω< 1000, plotting both Modal results (dashed lines) and KSW results (solid lines for 200 <ω< 1000); these show good agreement in the overlap. The lower two panels give the maximum KSW results for T-only and T+E in the range 1000 <ω< 3000).
