Comparison of covariance obtained in different ways. Upper row, from left to right: sample covariance from the SLICS, covariance estimated from Map correlation functions in the SLICS, model covariance under the large-field approximation, full model covariance including the finite field terms. Lower row: differences between sample covariance and other covariance estimates, normalised by bootstrap uncertainty of the sample covariance. We note that the colour bar changes between the three bottom plots.
