Kurtosis of SMHW wavelet coefficients. The grey bands show the 1, 2, and 3σ spread of kurtosis in 1000 Gaussian simulations. The red dots show the kurtosis of wavelet coefficients of the Planck SMICA map before the correction for the galaxy based model. The green dots show the kurtosis after the correction. The blue line shows the upper limit of the 2σ band for Gaussian simulations where the galaxy model was added to each simulation.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
