Correlation matrix (left panel) and normalized precision matrix (right panel) for galaxy clustering and galaxy-galaxy lensing data in the redshift interval 0.5 <z < 0.7. These are defined as C_ij/ and / respectively, where C_ij and refer to covariance and precision matrix elements respectively. In both panels, the upper triangular matrix represents the case without tapering, while the lower panel the case with tapering. The precision matrix is normalized such that diagonal elements are unity.
