Notes. We compare correlations measured from data with Monte Carlo averages over 100 Gaussian realizations. The simulations were processed through the different component separation pipelines in the same way as the data, but do not include any foreground component. According to this test, modal expansions are stable for a change of sky coverage, with measured correlations in full agreement with expectations from simulations.
