Correlation matrix of power spectrum amplitudes with respect to their mean value in the case of unaccounted foregrounds (left panel) and modelled foregrounds (right panel). The correlation matrix is normalized using the variance of the power spectrum amplitudes. We note that the colour map is truncated at a correlation level of 5 × 10-2. We estimate that all values below this threshold are too noisy to be cleanly represented and discard them.
